Very nice! I hope to do a video on a different route to carbon disulfide sometime: thermal decomposition of ammonium thiocyanate. The other product is apparently a guanidine compound, which could also be interesting to have!
The smell is based on thiophene, which is reported as being formed ( up to 2.7% of CS2)( ref JACS). Also, a lot of the sulfur ends up as H2S, which as you know is Very toxic. Nice video.
Use nitrogen instead of argon. If you don't have a nitrogen cylinder, you can make it, with ammonium chloride and sodium nitrite solutions. Add the gas upstream of the acid bubbler, so it can be dehydrated, too.
@@Hexazine0 lol, good point. But I was going to say that accessibility depends on location. If you're located in a place where I could ship it to you, I could provide you with some so you didn't have to put forth so much effort to acquire it. 🙂
Beautiful!! So much wonderful tar XD I must say it is genius in its simplicity, just burning with oxygen analogue. It makes me curious if in place of acetylene any other carbon source could be used (of course gas bubbling is most convenient than maybe propane or methane, but just cooking charcoal with an excess of boiling sulfur... total alchemy XD). Personally, I would try to make some crazy 120-160 degree reflux condenser to keep sulfur in the reaction flask and only push "volatiles" through (like boiling xylene keeping stable temperature). Now waiting for next video and more glass washing ASMR XD
@@ejkozan Carbon/sulfur works, but at considerably higher temperatures. I have seen it done in a ceramic reaction tube, with one closed end, and the other leading to the condenser. The tube is heated to glowing, and CS2 can be collected when condensed.
To purge the system you could probably use propane, butane, or natural gas. Much cheaper than argon and while still flammable, much less reactive than acetylene.
Thank you so much for teaching us about BASE Piranha! I only knew of Caro's acid, and use it often on Sulfur/Charcoal residues. I use an aq./iPrOH base bath already and the moment I started I cut back on scrubbing time by at least 75%. That being said, I recently started a channel too, and I hope to get around to doing another sulfur chlorination, and now you gave me another great project to get to. Thanks for making me aware of a 'safer route'. I know there's one more way involving heating carbon and sulfur in a sealed steel pipe to over 800C, but I can't be doing that shit...
Very nice video! A lot more convenient than the reports on ScienceMadness which use over 1000 degrees etc. I'm sure the yield can be improved a lot. Can't you use a lower temperature on the sulfur? If so; maybe a hotplate with magnetic stirrer to melt the sulfur? Spin the stuff around for better mixing? One thing though: Your beg for money to buy argon is pathetic, argon is not better than acetylene, you just used too little. Argon would have given the exact same result when used in the same amount. Also; if your CS2 smells like shit, try to wash it with NaOH, HCl.. what not, before distilling it
@@Hexazine0 its yellow and smelly and came over at 46°c It's a shame my hydroxylamine hydrochloride synthesis didn't work, I'd be making n2o and doing the barking dog
Purification to that level seems so difficult but just knowing how the pure stuff smells is enough for me to want to make some and purify it. Maybe activated carbon would be enough
@@Hexazine0 Carbon disulfide produced this way contain about 3.5% of thiophene as well as other organosulphur mess. 20 min shaking with saturated KMnO4 1:1 volume will clean it. (Ref “Small-scale synthesis of laboratory reagents” by Leonid Lerner)
and I quote: "Do not attempt it unless you are an experinced chemist." Nothing in this video lets me think that this has been done by an experienced chemist ...
The cleanup "add" was awesome.
Thanks!
The cleaning part was so satisfying.
Thank you! Will do it again if I carry out such a dirty reaction.

That would be nice! Looking forward to watch!
You would also get a substantial amount of thiophene. If you redistilled your residue, you could likely isolate this useful reagent.
Wow, thanks for showing the method, i actually never heard of it. And as always very good video, keep it up :)
Thank you for the support!❤
I really appreciate it!

CO2 would be fine for this
Or use a bit more acetylene
Vacuum purge and reprat with any noble gas or your acetylene
Another excellent video. Thank you!!!
I'm glad you like it!
Hi, thank you for this awesome video, can you explaine how to purify carbondisulfate fo gas chromatography use?
where are you located? I have access to CS2, but it's expensive.
Now I also have access to it, but it took me a lot of effort.
@@Hexazine0 lol, good point. But I was going to say that accessibility depends on location. If you're located in a place where I could ship it to you, I could provide you with some so you didn't have to put forth so much effort to acquire it. 🙂
Thank you! For now I don't plan anything with it, I just wanted to show this method so I can be helpful to other hobby chemists.
This is a good video ngl

Thank you! I'm also curious if paraffin with sulfur for example will give CS2 and will probably try it one day.
@@Hexazine0 I would try first some coal/charcoal. No hydrogen means no H2S generation. In theory just CS2 should be produced.

@@Hexazine0 Paraffin and sulfur gives a LOT of H2S.
@@michaelf7093 Wow! Good to know! It only a pity that it needs so higher temperature :(

Carbon dioxide works just fine for this, and for P4, too. I have two 9lb cylinbders (for soda fountains).
you can try ordering from acros, at least here (czech republic), I didn't need to provide any company info
Just googled it.
Seems that Ligma Baldrich ate the company and now charges horrendous prices on everything like always
Add alcohol to that base piranha and you get sodium peroxide precipitate 😊 I just read that today
из угля и серы не проще было бы?... или сразу карбид с серой греть и на выходе сероуглерод и сульфид кальция...
Nitrogen good enough for this application but argon is best😋

Probably something wrong if fart smells like this 😅
BTW I had a few fires too, argon is probably better to flush it with. I was just lazy
Nice! I'm so happy it also worked for you!

Sulfur compounds smell is really difficult to remove. I think that even the product from Sigma smells like fart.

For this reaction, CO2 will work every bit as well as argon, and CO2 is mondo cheaper.
