Making Nylon

[ainekification]

Oooo D:

[DixieNormas07]

...is he a wizard?

[RODALCO2007]

amazing !

[denelson83]

Putrescine is diaminobutane, Bobby, not diaminopropane.

[bonibonyrrk]

only if classes in my highschool were like this

[mysticmouse67]

Where's the SAFETY GLASSES???!!!!!!!

[babygirlrose1001]

wow tat's really long nylon!!!!..

[penna171980]

Do you make sutures and fishing line out of that??

[scienceman64]

The guy looks like bill Murray

[E2qNX8btraQ3zRD6J7fc]

He mentioned that a group of people are in the Guinness Book for making the longest thread of nylon. I can't find any info on this. Would anybody care to direct me to where I can find out more?

[XTwina]

what would happen, if you put the liqids in a bottle and shake it?

[KerryKworth]

@XTwina Since the reaction takes place at the border of the two liquids, agitation will cause the solution to react in the entire volume. The result is a mass of nylon that looks not unlike a phlegm ball from an elephant.

[dudeimamazingbeef]

YES!! That's 3 minutes of my 10 minute presentation on Nylon done!

[SylerHell]

pulling the nylon out look like pulling the noodle out XD

[jaganthechamp]

real good man.

[archangel1214]

what were the 2 chemicals he used? and can you make any other fiberous materials like this?

[sabram24]

man i was there 3 years ago when this was recorded. man that was a fun class

[sabram24]

@atsusamuno your a piece of shit.

[xxx666riley666xxx]

hey dude you cant get any u know y because u have a baby penis and i hope it falls off and satan eats for a snack

[CorbinAllred]

@sabram24 Man...!

[Jakub0071]

Yes I know

[fh1mahfanzai]

Question!, how come my nylon came out like a big chunk of a solid

[you238]

If you have the mixture of the diamine and dicarbonyl and just stir it up, they will just react all together, not at a nice thin layer like here

[j3ngen]

well, did you see how he poured the hexane diamine onto the side of the beaker? that caused the two substances to only touch in a small area. if there was a larger area, possibly pouring straight into the first chemical, rather than a tilted beaker, or if there was agitation, or stirring, then you would end up with a "glob" like product

[marker853]

we did this in high school

[fh1mahfanzai]

lol what h.s? this is orgo

[marker853]

palatine high school illinois

[Jakub0071]

n C4H8(COOH)2 + n C6H12(NH2)2 --> Nylon + 2n H2O

[bigmjfan1]

how do you know that... *-*

[CaptainObvious0000]

@Jakub0071 at the end it's (2n-1) H2O since you have a string, not a whole ring

[Alkoholtest]

I understand the theory behind hexanediamine and decandiachloride and that it reacts in the boundary between Water and Hexan - but why does it have to be aquious Sodiumhydroxide and not just water?

[CT6CrazyCanuck]

It could be that the aqueous solution of sodium hydroxide acts as a catalyst for the reaction, while water might not have the same effect

[MrDeshadow]

the diamine is basic and will pick up protons for water with its lone pair, making the lone pair on the nitrogen less reactive

[Alkoholtest]

Thank you.

[theawesomone]

now why can my prof do cool stuff like that?

[sabram24]

i loved this class. Was always fun going too.

[Ninensei18]

Wow, that was interesting!

[luneth62]

what solutions are needed?

[YoeriYoeri]

we saw this experiment today in class.

[anamu7tram]

are you an organic chemist

[spaceball1992]

cool my biologie teacher did that experiment in class today lol very nice.

[sakuranohana1523]

asking question .. so the hexamethylenediamine is in the cyclohexane solvent and the sebacoyl chloride is in the Aqueous Sodium Carbonate?

[denelson83]

@sakuranohana1523 The organic solvent is n-hexane. A straight chain, not a cyclic molecule.

[bluearmyspy]

sweet... all those organic chem classes and i know what he's talking about...

[babycuddle2]

Funny

[Br0wnies12]

Bob ... why did'nt you post these videos back in 2005-2006, I cud've done much better:(

[misterimpatient]

This really brought back fond memories of High School chemistry. My teacher at the Bronx High School of Science(Class of '74) was Mrs. Frank and I remember sitting mesmerized by this demonstration.

That doesn't explain why I went on to major in Electrical Engineering....

[melisenna]

we can do better, because we are chemical brothers XD

[thebestofall007]

awesome reaction. looks like a big loogi!!

[lunavixen015]

i counted 22 meters before he gave up

[kimjj4]

I got to do this in my organic chemistry lab

[Oernzen]

in germany i normally hate chemistry and physics..but this is some kind of special^^

i love these vids!

[endospores]

If the sebacoyl chloride is not fresh the string will break easily right?

[robertburkottawa]

The cpmpound is easily hydrolyzed (reacted with water) or oxidized. If it is not fresh, no reaction happens because there is no sebacoyl chloride.

[denelson83]

@endospores Actually, he didn't use sebacoyl chloride in this reaction. Besides, it can't form an aqueous solution because it actually reacts with water. He said he used a di-acid, either adipic acid or sebacic acid.

[Mankindux]

Guitar strings.

[reco1101]

what is the use of nylon thease days

[scobum]

these are great . thanx

[cycloneweaver]

The mushroom cloud thing scared the living s### out of me when I was six, Now it is just a bad memory.

Difunctional amide?
