i dont have one of those stiring plates i would have to stir it manualy but if i do then how do i place the cold water flask on top? does anyone have a good solution? or do i have to hold the flask stir and place the flask back down many times over again?
with a buddy of mine we chose to do this as our main experiment for our graduation thingamabob (dunno what it's called in english). We have about 4 weeks to go to make this, and we have about 3 hours a week to do so. it this manageable?
For the testing I recommend dissolving Luminol in sodium-hydroxide and add some hydrogen-peroxide together with a catalyst like Caliumhexacyanoferrat(III) or Hemine.
The bigger the Hemine contentration the more intense and the longer the reaction (to some degree).
The bigger the hydrogen-peroxide concentration the more intense but shorter the reaction.
Now I wonder if Caliumhexacyanoferrat(III) or Hemine really are catalysts, because the reaction is prolonged and more intense. Anyone knows?
man, someone who tried doing this would probably be branded as a meth cook to someone who doesn't know whats going on (with all the trash that this produces alone is enough to tip some people's assumptions). how long did this take to do in real life????
@thebestofall007 To research every reaction and work out all the conditions and alternative methods took about a year. (originally i started with the lab method, and down-converted it to the amateur method in the video)
Filming it and putting it all together took about a month.
However now that we have the working procedure of the video, it should only take an experienced chemist about a week to do.
I'd like to ask about the mechanism of the final step ... How does sodium metabisulfate reduce the nitro group? could you give me the mechanism ? and can be this method used to reduce acetone to isopropanol ?
All mine does is cloud up and spout out the beaker. It condenses on the beaker but its yellow and crusty. I don't see any cotton candy deposits on the bottom. I'm doing right now so hopefully I can figure out what is going on.
I am in college and my chemistry teacher was so impressed when I demonstrated the process to the whole class. She though I couldn't do it! I love your work and I hope I become like you in the future, a great chemist.
@alvinremixmaster08 You must be in a good college (guessing US though) as i asked to make luminol from OTC products, and they were concerned about the nitration in this.
Very well put together video. And for you guys thinking that thats the basics he's so right but with a decent amount of training you'll be fine. Just wondering wether or not you'd consider putting another synthesis video together, something like N-methylacridone and lucigenin. I have a synthesis if you're interested.
Wow, I watched this video when it initially went up and now watching it again, I actually understand what's going on and why. That makes me really happy haha. Keep up the great work! Hope to see more from you soon.
wow that was AMAZIN AWSOME. i tryed to make it in my organic classes but i don't have succesful. And I dedicated to looking for a technic, but i didn't find it. So now I see that you make it. It was a shock for me, but at the same time i feel very happy and suprise about it. congratualitations. keep making this excelent class of experiments.
Could you not have done an acid-catalysed hydrolysis on the diethylhexyl phthalate to give phthalic acid & 2-ethylhexanol, this way you could skip the second step. Also i noticed that your picture of diethylhexylphthalate is actually bis(1-ethyl)hexylphthalate, is it not supposed to be bis(2-ethyl)hexylphthalate?
@nurdrage after adding the sodium hydroxide to make disodium pthalate the bottom layer remained cloudy even after filtration and when i added the HCl some white fumes where noticed is this normal
@NurdRage I hope that was a joke, you shouldn't remove anything. You could rather mention the channel in a future channel-promotion video, or make a link to it in the description. I love your work, thank you.
@Poleschs i was basically saying "He's so awesome i am shamed to display my pathetic piece of work in his presence! I must hide mine so his may shine in brighter glory!!!"
hehehe yeah i'm joking :)
I definitely do agree he deserves a promotion and more subs.
@NurdRage I don't understand how you can get that good at chemistry. I don't get any of those hexagon chart things. I love chemistry, but I really don't get it. By the way, your videos are amazing. Thanks for posting them.
@NurdRage You show everything in such straightforward&fun way, that it gets many interesting in chemistry, including some folks, which believe to have no interest in chemistry. Maybe there videos are more advanced in technicall term, but many of this videos diminish the 'fun part' of it and its what get NEW folks interesting on subject and after all thats only thing which counts in the end.
@NurdRage I mean both of your guys' videos are useful.. You show how a person can make it using household chemicals. He shows how to do it with high grade lab chems and proper lab equipment, which would typically only be available to chemists.
Anyways, basic hydrolysis of the ester does not produce phtalic acid, but instead it will yield directly into deprotonised phtalate. Since hydroxide ions act as the nucleophyle. In basic conditions, carbonyl-groups are not strongly electrophylic so a stronger base then H2O is needed to act as the nucleophyle. No neutralisation takes place.
@Hydroxybenzeen i never said water was the nucleophile. When the hydroxide attacks, and after the alkoxide leaves, you get a carboxylic acid that is then deprotonated by the basic conditions. You won't directly get a deprotonated version since the hydrogen on the hydroxide has to magically leave before the alkoxide leaves.
After the carboxylic acid (in this case phthalic acid) is formed, it quickly gets neutralized under the basic conditions.
Even if you used stoichiometric NaOH, you would make disodium phthalate and not phthalic acid because the alkoxide would deprotonate the phthalic acid.
@LHCb42 looking at your statement a little more carefully: you say no phthalic is produced, but then you say the phthalic is deprotonated. This phthalic acid had to be produced somewhere. that is the phthalic acid i'm referring to.
@NurdRage Wait, huh? I'm referring to your statement, "to help separate the two products, we're using an excess of sodium hydroxide..." Excess is not needed. Stoichiometric will do.
@LHCb42 I don't see how i can predict the amount of the phthalic acid present in a given set of gloves until after i measure it. To use an excess ensures i capture all the phthalic acid i can reasonably expect in any given set of gloves from any manufacturer. Since they vary.
If i bring exact change to buy a coat then that's great. But if i don't know before hand how much it costs then it would be best to bring the amount i'm willing to spend, hopefully this will be excess.
What software do you use to draw out the organic molecules for the synthesis reaction? I've found several online, but I'm still curious which you use. :)
hey, I have a question. could you please explain how you obtained so much phthallic anhydride? I repeated nurdrage's process but ended up with half a gram instead of 13. I think I am doing something wrong but up until this point everything was going quite well.
this makes me worry for our future that to advance science to new heights we will have to rely on people most likely addicted to face-book I'm smart but not nearly this smart
lol dude that last statement about it only getting harder from this made my face go from amazed to crushed. now considereing going into inorganic chemistry now.
Two basic questions that I am too lazy to look up for myself:
1. Can the planning of a chemical process like this one be done with computer simulations and if so, do you know of a simulation software I could use to perform the reaction you did in this video?
2. Is there a way to capture waste and byproducts of the reactions for recycling or use in other processes, for example, capturing the NO2 when hydrolyzing 3-nitrophthalic anhydride?
This is an incredible video. What an accomplishment, NurdRage! It's awesome that you put so much time and effort into this, and it really made a fantastic video.The process was really well described and I liked seeing the illustrations of all the intermediate compounds. It made it really easy to follow. This is why I love chemistry!
Could you make a video were you explain wich is the reaction of the KNO3 + sugar, because i can´t find anything in internet and don´t know how to write that reaction, i suppose that produce CO2 and H20, but what happened with K and N?
Could acetone be used to dissolve and extract the diethylhexyl phthalate instead of isopropanol? I searched for some solubility information of diethylhexyl phthalate but couldn't find any.
As I did not have large amounts of isopropanol at the moment, I extracted DEPH from 50 grams of PVC gloves then with same IPA extracted DEPH from additional 50g of gloves (1h in boiling water bath, shaking periodicly. Glowes became crunchy). Next steps I did as you in this tutorial (however, without evaporating half of IPA and I used 2x amounts of NaOH and HCl) and got only 6.9 grams of phthalic acid.
@NADHHH Yield and recovery are quite variable and some gloves do better than others. As mentioned in the video if you need more you'll need to repeat the process until you get enough for the nitration step. Variability was anticipated and built into the procedure.
hi NurdRage. Great video! I just have two questions: can methanol (or ethanol) be used instead of isopropanol (for the extraction step) and can potassium metabisulfite be used instead of sodium?
I am a hard working A studen in high school trying to look for a collage to take me to the carrer of my dreams. since i enjoy Chemistry and Biolagy so much, i figuer what collages should i go to and what carrer usses both fields. I was think of the lines of a pharmaceutical chemist or a biochemist. what should i do to rank the most money
I also did this at home (Jor from sciencemadness), but I did not do a complete OTC synthesis. I nitrated phthalic anhydride, reacted this with hydrazine hydrate in glycerin, and reduced this with dithionite in ammonia :)
@AuraRisen We dehydrate it primarily to be able to purify it. if we took the raw material with all it's impurities we'd get a lower yield with even greater impurities in the nitration step. We also do it to reduce water content. The phthalic acid would release water into the sulfuric acid and turn into phthalic anhydride anyway. The water would dilute the acid a little and reduce yield. Starting from phthalic anhydride prevents that.
I get a large load of flak from commentors who come in with inflated expectations. If i tell them i'm going to show how to make something, they expect its simple, easy, cheap, useful. They rarely understand that messing with the cogs of the universe is hard, period. So i need to crush their expectations and get rid of them before they clog up the comments with stupid complaints like "You said you'd make a space shuttle! you're supposed to use household materials!" (face-palm)
Hello NurdRage! As a senior chemistry student who loves org.chem I have 2 questions: Do you know where I can find the mechanisms for the hydrazine condensation and the Al/ NaOH reduction steps? Also in the step of nitrating the benzene ring, isn't possible for the sulfuric acid to hydrolyze the anhydride instead of reacting with sodium nitrate?
@AuraRisen You are partly correct. Yeah we don't care about the sulfate ions because there are super weak base. We don't worry for the H+ not because they are electron deficient, but because there is no water in the nitration step to. H+ does not attack the carbonyl directly. It simply protonates it to make the carbon more electrophilic and help a nucleophile such as water to attack. So as NurdRage correctly replied, no water? No hydrolysis...
I love your videos I'm not even a chemist and I find everything really interesting. Just out of curiosity do you know how to make drugs like meth and stuff. Not that I actually want you to demonstrate how to I was just curious if you understand all the science involved and not that you would make it but could you that is do you have the knowledge

MnSO4+2KMnO3-->K2SO4+Mn(MnO3)2
or any other case in witch there is the same metal in the cation and anion

Can you replace sodium nitrate with KNO3?
I know that both can be used interchangeably for most purposes, but I just wanted to make sure.
Thank you for your time.

@yellowmetalcyborg yup, go for it. although you'll need to recalculate the moles.

This is an incredible video. What an accomplishment, NurdRage! It's awesome that you put so much time and effort into this, and it really made a fantastic video.The process was really well described and I liked seeing the illustrations of all the intermediate compounds. It made it really easy to follow. This is why I love chemistry!

Great video! Can 91% drugstore isopropanol be used? Or, could isopropanol gas-line antifreeze (Iso-Heet) be used?
ChemCrazy81 10 months ago
@ChemCrazy81 91%? i personally haven't tried it, i think it should.... but you might need more of it.
Try it and see if it works for ya, hopefully its cheap!
i'm not sure the composition of iso-heet so i can't really say it if should or shouldn't work.

I have a question:
Could you make a video were you explain wich is the reaction of the KNO3 + sugar, because i can´t find anything in internet and don´t know how to write that reaction, i suppose that produce CO2 and H20, but what happened with K and N?
Thanks, and excellents videos.

48 KNO3 + 5 C12H22O11 = 60 CO2 + 55 H2O + 24 K2O + 24 N2
K2CO3, KNO2 and other things are formed like various organics and carbon are formed which give funny smells.

Can PVC cement be used for the Diethylhexyl Pthalate rather than vinyl gloves?
Just asking because I have it on hand.

Could acetone be used to dissolve and extract the diethylhexyl phthalate instead of isopropanol? I searched for some solubility information of diethylhexyl phthalate but couldn't find any.
Great work, a student from Croatia.

As I did not have large amounts of isopropanol at the moment, I extracted DEPH from 50 grams of PVC gloves then with same IPA extracted DEPH from additional 50g of gloves (1h in boiling water bath, shaking periodicly. Glowes became crunchy). Next steps I did as you in this tutorial (however, without evaporating half of IPA and I used 2x amounts of NaOH and HCl) and got only 6.9 grams of phthalic acid.

@NADHHH Yield and recovery are quite variable and some gloves do better than others. As mentioned in the video if you need more you'll need to repeat the process until you get enough for the nitration step. Variability was anticipated and built into the procedure.
NurdRage 11 months ago
hi NurdRage. Great video! I just have two questions: can methanol (or ethanol) be used instead of isopropanol (for the extraction step) and can potassium metabisulfite be used instead of sodium?

@YuLeeHen 1. better with isopropanol, 2. yes.

@NurdRage hello Nurdrage, first off nice vids.
I am a hard working A studen in high school trying to look for a collage to take me to the carrer of my dreams. since i enjoy Chemistry and Biolagy so much, i figuer what collages should i go to and what carrer usses both fields. I was think of the lines of a pharmaceutical chemist or a biochemist. what should i do to rank the most money
thx miesrah12
miesrah12 11 months ago
Potassium metabisulfate / potassium nitrate instead of corresponding sodium salts is OK, right?
Can I use 65% nitric acid instead of nitrate or nitrating mixture should not contain water?
NADHHH 11 months ago
@NADHHH 1. yes 2. better if there is no water

Very nicely done! A completely OTC synthesis!
I also did this at home (Jor from sciencemadness), but I did not do a complete OTC synthesis. I nitrated phthalic anhydride, reacted this with hydrazine hydrate in glycerin, and reduced this with dithionite in ammonia :)

Hello NurdRage!
Great Job as always! I have a question: why did you dehydrate to phthalic anhydride?
If the molecule is not dehidride the wouldn't the (H2O-NO2)+ attack at the same spot?
Thanks!
AuraRisen 11 months ago
@AuraRisen We dehydrate it primarily to be able to purify it. if we took the raw material with all it's impurities we'd get a lower yield with even greater impurities in the nitration step. We also do it to reduce water content. The phthalic acid would release water into the sulfuric acid and turn into phthalic anhydride anyway. The water would dilute the acid a little and reduce yield. Starting from phthalic anhydride prevents that.

At the end of the video: "Just know, this is very simple chemistry. It only gets harder from here."
Thanks. You can't go for one video without crushing expectations at least 3 times, can you? =D
pcred566 11 months ago
@pcred566
Hehehe
I get a large load of flak from commentors who come in with inflated expectations. If i tell them i'm going to show how to make something, they expect its simple, easy, cheap, useful. They rarely understand that messing with the cogs of the universe is hard, period. So i need to crush their expectations and get rid of them before they clog up the comments with stupid complaints like "You said you'd make a space shuttle! you're supposed to use household materials!" (face-palm)

@NurdRage Oh, I see. Well, better than having them believe that they're going to be able to take the easy way out.
pcred566 11 months ago
Hello NurdRage! As a senior chemistry student who loves org.chem I have 2 questions: Do you know where I can find the mechanisms for the hydrazine condensation and the Al/ NaOH reduction steps? Also in the step of nitrating the benzene ring, isn't possible for the sulfuric acid to hydrolyze the anhydride instead of reacting with sodium nitrate?
Kudos for your videos!
ChemistDrummer 11 months ago
@ChemistDrummer I'm Not a EXPERT but i'm learning.
I don't think so, because H+ doesn't have electrons avaible to attack and (SO4)2- is a super weak base.
Correct me if i'm wrong!
AuraRisen 11 months ago
@AuraRisen You are partly correct. Yeah we don't care about the sulfate ions because there are super weak base. We don't worry for the H+ not because they are electron deficient, but because there is no water in the nitration step to. H+ does not attack the carbonyl directly. It simply protonates it to make the carbon more electrophilic and help a nucleophile such as water to attack. So as NurdRage correctly replied, no water? No hydrolysis...

Research
1. amide formation
2. synthesis of dithionite and sulfides by dissolving metal reduction and reduction of aromatic nitro groups by dithionite and sulfides
3. No, where does the water come from?

I love your videos I'm not even a chemist and I find everything really interesting. Just out of curiosity do you know how to make drugs like meth and stuff. Not that I actually want you to demonstrate how to I was just curious if you understand all the science involved and not that you would make it but could you that is do you have the knowledge
