  • how could you get rid of that sulphate in order to get freebase hydrazine?

  • @dariumzleso

    Mix the sulfate with a stoichiometric amount of base and distill off the hydrazine.

  • @98JMA

    like if i've got 1 mol hydrazine sulfate i'll mix it with 1 mol NaOH?

  • @dariumzleso

    No. Look at the balanced equation, and find how many moles of base (NaOH) you need per mole of sulfate for the conversion. That will give you your ratio.

    If you cannot understand the math and simple theory involved, I don't think you should attempt it.

  • @98JMA

    I'm studying chemistry but i'm italian so there might be some misunderstandings.

    however, like you say, i have to calculate the number of moles of base that stoichiometrically fits the moles of the sulfate ion (SO4), right? not the interely hydrazine sulfate.

    for example, x grams of hydr. sulfate ---> moles of sulfate ions in it = moles of base to be used. Correct?

  • @dariumzleso

    Not exactly. Look at this balanced equation;

    N2H4(H2SO4) + 2 NaOH = Na2SO4 + 2 H2O + N2H4

    As you can see, one mole equiv. of hydrazine sulfate reacts with two mole equiv. of base, so, you need to use twice the molar amount of NaOH as you do the Hydrazine Sulfate. For example, if you used, say, 30g of hydrazine sulfate, then you will need to use 18.44g of NaOH.

  • @98JMA

    If you attempt this yourself, though, be extremely cautious - pure hydrazine attacks glass at elevated temperatures, so a metal still must be used, it is incredibly toxic, highly corrosive, a skin sensitiser, a known carcinogen and has dozens of other highly adverse health effects. DO NOT attempt unless you have access to a very powerful fumehood or glovebox, are wearing full PPE, including a face shield, full PVC suit and respirator, chemical splash goggles and heavy

  • @98JMA

    neoprene gloves and have a lot of experience handling these materials. The distillation must also be carried out under argon or nitrogen, as pure liquid hydrazine reacts violently with air and sometimes moisture.

  • @98JMA

    Ok, thanks.

    I suppose this basing procedure is also suitable for other compounds, right?

    an HCl salt instead of a sulfate for example

  • @dariumzleso

    Possibly, although you will need to make sure that whatever acid you use can protonate one of the amines on the hydrazine. Also, you would have a significant loss in yield with the monohydrochloride salt, as it is much more soluble than the sulfate.

    The best way to find out things like this is just to experiment on a small scale until you find a procedure that you like.

  • @nurdrage

    

  • Hi .. i was looking for some videos of hydrazine synthesis but i dont have methyl ethyl ketone becouse were i live it's imposible to get the methyl ethyl ketone.i have a very old proces fore making hidrazin.you mix sodium bleach and ammonia, and heating up to expulse the amounnia that has dont react .. then you boil torediuse a have the solution and cool it .. later you add an sulfiuric acid solution and the hidrazine sulfate precipiteits out,i have try this method but i can't get it working.

  • @gboneu617

    The reason that it doesn't work is because, well. . .it just won't work. Try looking for MEK on eBay . . .it's pretty widely available.

  • What do you use hydrazine sulphate for?

  • @shoottherunner8008

    He uses it in his luminol synthesis.

  • Since sciencemadness and many other open source areas are temporarily down in protest to the SOPA act, can I ask how to convert the hydrazine sulfate into hydrazine hydrate?

  • @watchmefall555

    Try distilling the sulfate with a stoichiometric amount of aqueous base and adding an appropriate amount of water to the distillate.

  • @Victorjatem2 I think it's that rock/wood like thing going around in the jar may be magnetic and a magnet is in the stand thing spinning

  • WTF

    how the hell is possible to the liquid be rotating?

    there is nothing that make in rotates

    how is this possible?

  • @victorjatem2

    A small magnet is rotating inside the hotplate which couples to an external teflon-coated magnet inside the glassware, causing it in turn to rotate, mixing the chemicals.

  • As to the peroxide-ketazine process mentioned at 8:00, what kind of catalyst would be required, and what concentration hydrogen peroxide would be required? It just seems like insanity to mix bleach and ammonia.

  • what is it even used for

  • @scor9977

    See his video on making luminol.

  • lol thks for telling us about the missing 2 you took all the fun of checking if your equations were balanced.

  • @PyroDesu haha...piece of wood. you replied much nicer than I could've. piece of wood... hahaha

  • methyl ethyl

  • could acetone be used instead of the methil ethilketone?

  • @192asso That very question is answered near the end of the video.

  • @PyroDesu ahaha,yes,I heard that after asking my question,thank you!

  • Noob question, what is this for?

  • im not a nerd but how is the piece of wood in the beaker spinning?

  • @GrandNecro That's not a piece of wood, that's a magnetic stir bar. The plate below it has a rotating magnetic field that spins the bar.

  • I bet this guy could make meth with the best of them.

  • How much ammonia should I use if I use household ammonia?

  • can i get hydrazine by mixing ammonia with hydrogen peroxide?

    2NH3 + H2O2 -> N2H4 + 2H2O

  • @TheMrWeedy That won't work.

     More likley you'll get Nitrogen and Water. (They may react violently)

    2NH3 + 3 H2O2 -> N2 + 6 H2O

  • Thank you! This is a great synth, Keep up all the great work.

  • can formic acid replace sulfuric acid to create hydrazine monoformate?

    only problem is formic acid isn't available over 90% at a reasonable price, and some of the hydrazine might dissolve, but other than that, think it will work?

  • Well, I know Bleach + Ammonia creates Musterd Gas, so how safe is this to do, if it were done inside of a fume hood with a Chemistry teacher (all safety precautions taken, gloves worn)?

  • @TheQgvFactor which moron told you the blatant lie that bleach and ammonia make mustard gas? It makes toxic chloramine, but certainly not mustard gas.

  • @NurdRage Ah, alright then, thank you for clarifying that. Also, I'm doing your home-made Luminol experiment for my chemistry class (found your videos today, just got the green light to go ahead with it from my Chemistry teacher) and I was wonder, approximately how much does it cost? Thanks in advance.

  • @NurdRage Yeah I believe Sulfur Mustards have SULFUR in them. NaOCl + NH3 ---> C4H8Cl2S... S...?

  • @NurdRage it's a popular internet tale, i believe, originating from the Anarchist's cookbook...

  • @TheQgvFactor

    If it were that easy to produce mustard gas...we all would have bigger problems...

  • @TheQgvFactor myfanwy94 died messing with this kinda stuff, you may make hydrazine by accident with ammonia and bleach with excesive amonia i dont recomend doing this, mustard gas is infact made using only two very well known chemicals, i would tell you so u dont do it accidently but sum jack ass would read the comment combine the gasses and kill himself or others, making hydrazine sumtimes generates phosgene gas, look up phosgene gas i spelled it wrong but you figure it out

  • @TheQgvFactor In general, when done in a fumehood with proper safety precautions, none of the gas will escape into the room. Your chemistry teacher should know how to do this stuff safely.

  • Where did you get you're lab equipment?

  • @ConorC96

    He's a research chemist.

  • you can get MEK from any fiberglass or composites company we use that to clean all the time

  • what gas is this producing

    

  • Comment removed

  • best

  • You're using a voice synthesizer/distorter, aren't you?

  • @PyroDesu No, that's his real voice. In fact, he dubbed the Saw series...

  • @jazerazo He seriously dubbed the Saw series? Where did you find that out?

  • what is the Stoichiometric ratio of hydazine sulfate and ammonia to produce hydrazine or would it be more effective to oxidise amonia and distil the hydrazine

  • @h0meIandsecurity I think one way to prepare sulfur is by burning Mg in SO2. I am not sure if it works but I seem to recall there were 2 webpages that suggest that it works. It certainly works when you burn in CO2 and you get carbon.

  • any idea --- Sent From NurdRage's AppRats (Facebook App)!

  • 1:23 you say that small amounds of hydrazine is produced from the reaction, is it possible to condence the stray hydrazine and mix it with some sulfuric acid as it comes over? would you me able to get a small bit of a higher yield?

  • i have no idea what i would use that chemical for but i just like watching :)

  • From where can you get methyl ethyl ketone in Canada? Ace hardware, rona, reno and home depot don't seem to have it.

  • Are you still working on the lead dioxide electrode video (as a followup to your MnO2 electrode video)?

  • I will be trying this and the luminol synth in the next coming weeks. Probably wont film it as there is no need for a worse shot version of the same reaction but I will let you know how it goes.

  • I feel like daring my friends to watch some of your videos to see if they can understand it >;3

  • hydrazinesulfate (dot) org

  • @h0meIandsecurity

    Is this your homework?

  • @thompsonstudios The point is to learn, however, considering you probably don't do much of that, stop watching the videos.

  • WHAT IS THE POINT OF THIS

  • we appreciate all the hardwork you put into your videos nurd

  • I just bought some household ammonia from the supermarket. How can i determine its concentration?

  • @oboeizzle

    Try a volumetric titration versus hydrochloric acid or something, and using the calculations for that to determine the concentration of ammonia.

  • I don't understand almost 95.99% of what you're talking about but I like watching your videos.

  • that seems very easy&straightforward., I got the chemicals so I may try this.

    NurdRage, why not show some more complex reactions?

  • @UTubeisSHIT523441 check out my video on making luminol, the complete guide version. :)

  • @NurdRage thank you. I already watch all your video man:) The videos on luminol is especially cool, really great work.

    I watched your video on plating with MnO2 and I have one question: Do this only works on titanium metal or can you use other metals as well?

    I searched on Google but didn't find any (good) resources on plating with lead dioxide, just the sciencemadness forum post.

    Thank you.

  • @NurdRage why dont u ever show ur face?

  • do not try at home

  • That was fun. I'm thinking about doing it again with calcium hydroxide and ammonium sulfate in lieu of ammonia (I have plenty of those), and calcium hypochlorite solution. I don't know if the sulfate ion will interfere with the ketazine reaction.

  • Hi NurdRage,

    I did this procedure just as you said but it never fase separated.I used 250ml 12% ammonia maybe it's too low. Do you think bubbling NH3 from your sodium nitrate synthesis in water would give me an high enough ammonia concentration?

  • Does anyone know if more dilute sulfuric acid can be used? Say 80%? Then just use more acid?

  • Why dont you want to be seen? I know why. But you just want to explore science! Yay! YOUR DOING A GREAT JOB!

  • @Nurdrage: What catalysts are needed for the process using H2O2 instead of bleach? I don't see why this reaction won't proceed without any catalysts? I prefer using 35% peroxide (of which I have a lot) to using 6% bleach.

    PS: Great video. I absolutely love these more advanced videos dealing with organic chemistry. Keep it up!

    PPS: Nice to see you on the Sciencemadness board. :)

  • @norscience

    From Handbook of inorganic chemistry, 2003, by Pradyot Patnaik:

    (..) ammonia is oxidizes with hydrogen peroxide in the presence of methyl ethyl ketone, acetamide and disodium hydrogen phosphate at 50C.

    Reaction products are butanone azine and 4H20

    I am actually planning to try this way because I have lots of 50% H2O2 and I suppose this method should be less dangerous than with bleach. I will use acetone instead of butanone.

  • I did this with 250ml 25% ammonia, 50ml acetone, 450ml 4-5% hypochlorite bleach followed by 2 extractions with toluene and neutralisation with sulfuric acid and yield was extremely low - less than one gram hydrazine sulfate. I accidentaly got some dusts in reaction solution. Also some white precipitate flakes formed between reaction solution and toluene layer (without sulfuric acid). Have you any idea where I get wrong?

  • @NADHHH

    Left it overnigt and performed again few extractions with toluene - each extraction with ~200ml toluene yields about one gram. I think it is because large volume of reaction mixture (I used 4% bleach).

  • @NADHHH Absolutely no idea at all, did you use diluted or concentrated sulfuric acid?

  • @NurdRage I used 98% acid mixed with distilled water. Like in the process. It changed color but I never got any salt precipitating out, unlike in your demonstration.

  • @TakronRust no idea what's wrong then. but your bleach sounds far too dilute. maybe try something stronger next time.

  • I got the Ketazine layer on mine and separated it. When I got to the hydrolysis step,when I added the sulfuric acid, it turned a red/brown color like apple juice and I never got any salt. Would you have any idea what happened?

  • @TakronRust nope, did you use diluted or concentrated sulfuric acid?

  • Can the methyl ethyl keytone seperated from the final step be re-used to make more hydrazine sulphate?

  • Hello fellow nurd (?), we did this experiment in college obtaining acid hydrazine sulfate, but we didn't used MEK or acetone at all, the resulting substance was pure too but our yield was about 23%. Our procedure was almost exactly the same apart from the MEK, so my question is if our lower yield was because of the absecene of MEK or just experimental errors. Anyway great video!

  • I have a video (actually 2 parts) up of a working Hofmann rearrangement for hydrazine sulfate. I borrowed a handy concept from this video which I would not have thought of without it. Thanks!

  • @UC235 did you give credit where its due? :)

  • @NurdRage Of course I did.

  • @UC235 i already messaged you about that.

  • would Hydrazine Sulfate still work as a rocketfuel or would i have to make just hydrazine?

  • You mentioned a catalyst right? I might find a site that sells catalysts.

  • How does the stir bar work?

  • @NurdRage What happened to your heater's knob?

  • What can you do with the Hydrazine sulfate product?Is liquid Hydrazine comparable to nitromethane in volatility?I think Hydrazine was once used as a exotic fuel for race cars.your vids are fascinating to watch.....

  • Is it weird that I'm 15 and love chemistry?

    I've been watching all of your videos because I want to learn about it more... The only physical chemistry I've ever done was putting zinc in hydrochloric acid and using a tube to make hydrogen bubbles with soap water. That was fun. lol

  • @1jbrit1

    Hey, same here, liked chemistry scince I was 8 I believe. I even got my own organic chemistry book when I was nine. :D

  • I think that acetone ketazine could be salted out of water by adding a salt, for example sodium chloride, until the water is saturated of it, pushing the ketazine + acetone out making a second phase. MEK is fairly soluble in water so it too could help to rise the yields of the MEK variation... Nice vid!

  • @Palizasadomicilio I tried salting but it didn't work. Its a good idea though, but you should still go with either distillation if using acetone, or just go with MEK for phase separation.

  • How would you recommend making concentrated ammonia solution, NurdRage?

    Perhaps combining a hydroxide salt and an ammonium salt and bubbling the evolved NH3 into a chilled container of water?

  • When I tried it, my methyl ethyl ketazine did not separate out. I stirred household ammonia and methyl ethyl ketone together and then added bleach slowly. I waited and waited. separation never took place. Do you have any tips?

  • @61slugbug what concentration was the ammonia? greater than 20%?

  • I love this channel 

  • can you make other hydrazine salts by adding different acids?

  • show ur face damnit

  • @abutosin u first damnit

  • @NurdRage lol

    

  • @NurdRage Why do you hide your identity anyway? I mean, i dont blame you or anything, especially because it can affect your job.

  • @NurdRage  so is this guy a terrorist?

  • A good video you could do is about prussian blue/yellow/red etc and how to convert eachother :-)

  • l0l 6:25 almost looks like crack or meth lab lol

  • @xPyrotechx missing an anime or missing an amine? if it is an anime can you tell me?

  • it's excellent to see you doing the advanced sections! :P this is the kind of thing youtube is seriously lacking in terms of chemistry. I will be donating some more advanced videos once I'm done fitting bathrooms and sanding floors as a christmas present for mum. i have successfully demethylated 4-Allyl-2-methoxyphenol to the corresponding catechol, if this is of interest. I did so using a lewis acid. more to come, eventually. please continue to include the more advanced sections

  • Awesome work, I think u're the first hobbyist to master the ketazine process :)

    I made some HS from urea and bleach, it is very time consuming and volatile process. Once had a nasty runaway too..

  • Your always explaining how to do things, make one on how to do your voice! =P love your work

  • @xPyrotechx ah crud, you're right. i'll pull the video and fix the mistake when i have the time, probably next week. thanks for pointing it out.

  • how do you make nitrogen triiodide?

  • i just watches this cuz your voice if funeh! XD

  • thanks for putting this great collection of vids on here can you show a good Synthesis for silver nitrate as i want to plate some glass bits & bobs with mirror silver as you done in one of your vids....is it as easy as just desolve silver in nitric acid ..

  • @tobelleys Didn't I?

  • @NurdRage hey nurdrage, im not sure if what you using was common since im a beginner but what was that thing at the bottom of the glass you were using to stir the compounds?

  • @silentbl00d

    It's called a magnetic stir bar . . . . .inside the blue machine there is a strong magnet attached to a spinning motor. The bar inside the flask is also a magnet (coated in Teflon), so the two attract each other. As the motor with the magnet spins, so does the one in the flask because of the magnetic fields. As for your other question . . . .erm . . . . yes, they ARE common in professional labs like Nurd Rage's, but are usually very expensive to buy - try making your own!

  • I have no Idea whats going on or what your saying :(

    But I keep watching?

  • Am I dumb, or how can you spin the ... well, the things inside the ... wow, english fail ftw. I hope you know what I mean but... I ssee some buttons, but how the ... *confused, cant tell what I want to ask*

  • @PaintNETutorial i have a video on it, just type "lab equipment magnetic stir plate" into youtube search. :)

  • @PaintNETutorial its megnets, you know the metal that sticks to other metal

  • Although there have been many other influences, your channel is has played its part in rekindling my interest in becoming a chemist. Videos like these helped me learn enough chemistry on my own to pass my CLEP test with a high score and receive college credit necessary for my associates degree. I believe that that test was very influential in helping me land a job as a laboratory technician a month ago. Sadly I was just laid off, but I walked away with $2K, some experience, and a good reference.

  • @Libertarianist awesome to hear that my videos did some good.

    Good luck in your future endeavors and employment.

  • yaaaa!! i know how to make meth now :D

  • Nurd Rage, You are the bomb. I enjoy your videos and have learned a lot about chemistry and safety, much more interesting than the out of date college videos on safety and lame "experiments" in low level chem classes.

  • Hello NurdRage, i want to play a game

  • @CyRz1 LOFL xD!!

  • How does your stirring apparatus work?

  • wat can u do with it?

  • Why is Jesus' good name do I need to make Hydrazine sulfate? lmao

  • @DBDMotorsports

    It's an interesting reaction, and it's quite fun and you learn about the chemistry.

    There is also some neat things you can do with Hydrazine sulfate like making copper mirrors and some explosives can be made from it

  • how did u stir the solutions? i don't see any objects doing it.

  • @NurdRage you should just leave these kind of videos to write ups, and just stick with the noob videos. This video = 12k+ in 2 weeks, Steel wool video = 15k+ in 2 days.

  • @badass6996 i will always produce a variety of videos for a variety of skill levels. The advanced chemists need videos too.

  • can you make BZ-reaction?

  • so what are you going to do with the hydrazine sulfate?

  • if you add 0.5 mole to the Ammonia would it oxidize it to nitric acid

  • @42supernerd no

  • @42supernerd LOL!

  • i like how you go out of the way to stay anon

    though, i dont think i've seen any of your videos deal with illegal activities(i havent watched them all, so there may be one or two) i like that you do stay anon so ypu dont have to be afraid to post any video should it deal with *ahem* questionable activities :)

  • A comment on ammonia solution... Blueprint machines commonly use concentrated (24 or 26 baume [25.5% or 29.4%]) ammonia solution; much stronger than the strongest concentrations sold for cleaning purposes. Although blueprinting is much less common these days than it once was, there are still a few suppliers around who carry the concentrated solutions for that purpose. The price may be as little as half what you'd pay for the same strength ammonium hydroxide from a chemical supplier.

  • could the bleach be substituted for a solution of calcium hypochlorite pool chlorine? also, would you be able to extract hydrazine form the hydrazine sulfate by adding calcium hydroxide then filtering?

  • @Dunescha

    I think so, you'll have to work out the stiochometry though

  • can you make a video on making a powder that when lit on fire makes different color flames

  • Thanks for all the great vids. I was wondering if there are any books you could recomend for an novice interested in chemistry? Once again...thanks.

  • Chemiluminescence of luminol and its synthesis from easily available chemicals

    By Simsa, Daniel; Skopal, Jan

    From Chemicke Listy (2008), 102(11), 1017-1019. Language: Czech

    I found this searching for hydrazine sulfate in the scifinder. I let you a pm with the abstract.

  • Hmm, I was just wondering if it is possible for you to give us a video about how to make acetone?

  • @rosabellis I bet it could be done via catalytic oxidation of isopropanol over hot copper. But why would you want to make it? Every hardware store sells it by the gallon.

  • Could you use Hydrazine sulfate to make Hydrazine monohydrate?

  • @NurdRage are You a chemistry teacher?

  • Do you know how to cook crystal meth?

  • @HasteTheDays buahahahahahahahahhaahahha

  • @NurdRage Is there a way to make dyes with that? Like azo or diazo.

  • @g3ov4n12 i suppose, any particular dye you'd like to see?

  • you can get 35% hydrogen peroxide from grow shops

  • @sparky100able go for it.

  • @sparky100able Yep, it can be bought. I very recently ordered and received 16 oz. (.95L) of 35% H2O2 from a health food store. Cost was a bit high at US$22. Best online prices I've seen were in the neighborhood of $50 per gallon (3.79L). Shipping it is costly, though, so I didn't overpay by so much as it may seem.

    So, then: how to use it, NurdRage? You mention catalysts...

  • i don't understand a thing, but you and chemistry are way to cool to not watch your videos =D i follow latin so i only have 1 hour of chemistry =( (explains why i don't understand a thing lol) but keep going, it's so fun and cool to watch you =)

    ps: if you know a very easy but cool to perform reaction or something i could use for school, that would be awesome =)

  • How make AlCl to Al?
