Rhodanide - 2021-03-15
OH LOOK, IT'S THAT TIME OF YEAR WHERE I MAKE A VIDEO AGAIN! Yikes, this one took me too long. Was pretty fun to make though, can't deny that! Anyways, this video is about the synthesis of Perthiocyanic acid, a strange organic heterocycle made from Inorganic starting materials. I hope you enjoy!

You may not upload often, but man, that's 25 minutes of quality content!
Something comes to mind though... could Perthiocyanic acid be the same compound as the "perthiocyanogen" you made in another video? It was made in a similar way (thiocyanate in an acidic & oxidizing media), looked the same (yellow-orange powder), and seems to behave the same too (insoluble in cold water, soluble in ethylene diamine.)
(Oh, also, dipping your pH paper straight in the reaction mixture is a sin! ^^)
@Rhodanide "I don't recall if the Perthiocyanogen dissolved in anhydrous Ethylenediamine as it was made before I had that"
Are you sure? Because it sure looks and sounds like you're dissolving it in ethylenediamine at 18:53 in that other video. (Perhaps not anhydrous, but would it make a difference?)
@piranha031091 Oh yeah, you're right! Good catch. Well, if it did dissolve (looks like a lil' bit) then it definitely wasn't green like this was. Looked orange.
@piranha031091 also that Ethylenediamine had to have been anhydrous, because that's the only form of en I've ever owned. Must have already had it then, I guess.
@Rhodanide Well, if I look at this video, it's orange-brown-ish for a second or so before turning green. The other video cuts too quickly to really tell.
Maybe if you still have the full clip somewhere you could check?
Perthiocyanic acid is different compound than parathiocyanogen.
Perthiocyanic acid is formed by decomposition of isothiocyanic acid (together with carbonyl sulfide): 3HCNS --> H2S3C2N2 + HCN; HNCS + H2SO4 + H2O = COS + NH4HSO4. It can be considered as isomer of sulfur dithiocyanate S(SCN)2 (but it isn't the same compound). Structure of this compounds is here: https: //pubs.acs.org/doi/10.1021/jo00830a087
Parathiocyanogen is formed by polymerization of thiocyanogen (SCN)2. Thiocyanogen is unstable at room temperature and in the presence of water, so it is just short-lived intermediate which immediately polymerized (however preparation of solution of (SCN)2 in organic solvents at subzero temperatures is very well described). For making parathiocyanogen you need some oxidizer (this can be compared to oxidation of sulfide to polysulfide) like chlorine or bromine. There are other methods than oxidation by halogen in aqueous solution, like anodic oxidation of thiocyanate in MeOH or in melt, decomposition of Cu(SCN)2 or oxidation of molten thiocyanate by Fe(III), Cu(II), Sn(IV) or Co(III). Parathiocyanogen is a linear chain polymer (and not cyclic compound like perthiocyanic acid).
He's back! And with some nice organic yellow chem too! Lovely synthesis, and as a grammar Nazi I can well understand your frustration on spelling mistakes. No worries about the late upload, though. The wait was worth it
Much appreciated! I remember once, a while back I completely scrapped a video render to fix a single spelling mistake. That was.. something else.
@Rhodanide I feel you, no shame there
Glad to see a new video! We really enjoyed the reactions, especially nickel. Looking forward to more videos.
Isopropanol maybe could work as recrystallization solvent
Just gonna flex Sigma like that, okay Oliver :)
That was like 20 bucks that I snagged off of some eBay schmuck
@Rhodanide the only reason you didn't complain about the price
The lead salt looks like a scrambled egg before you finish frying it. Probably tastes the same too.
I'm out of coffee filters, can I use yours after you are finished weighing out your KSCN?
Yellow chem good?
You must be Explosion & Fire arch nemesis
22:44 wonderful results
Yellow chem very good! Oh, I am still working on getting you that carbon tetrachloride. I just need to distill it and it'll be ready to go. Sorry for the delay. Between my day job and my business, I've had absolutely 0 time to do very much lately.
Where did you get carbon tet?!? From an old fire extinguisher like Tom?
My man, say less. We all got so much stuff going on. I understand 110%.
@Chemistry of Questionable Quality from several old "fire bomb" type extinguishers. I paid out the ass for a bunch of them (one if which was labeled as carbon tet, but was not 🙄) and now have to distill it all to clean it up a bit. I'm hoping to have that done this weekend and to start sending out samples to various channels by the end of next week. Fingers crossed that it works out that way. 🤞
@Rhodanide thanks for understanding. Life can get hectic very fast. Especially when dealing with 2 jobs, a family of 5, health problems, trying to help my parents out, helping so many others out, getting things fixed like my truck, etc. It seems like it never ends. And yeah, it also seems like it's like this for everyone these days. We're all over worked and under stimulated. I need a chemistry vacation. If that isn't a thing it will be when I'm done. Lol!
Beautiful synthesis Holden
😁
So, what's your chemistry grudge, if it's not yellow chemistry?
I'd love to see trithiocarbonic acid, only ever read about it
"A reddish, ill-smelling oil"
Sounds...
Fun...?
@Rhodanide After watching the video again, only now do I see a reply to my comment from one of my favorite chemistry YouTubers, thank you YouTube for never giving me notifications.
But anyway, thanks for the reply and the video was weird and amazing, the best kind.
I'm never looking at Nickel the same way again...
Ok, this yellow chem gets a pass.
Phew
fuck it, yellow chem!
THAT'S THE SPIRIT!
thanks man.
very much.
Cool Chem ! Nice one.
Thanks, aga!
23:00 , very weird! And at 23:35 ? What the hell is that!?! Very cool and weird at the same time! I wonder what is going on there?
Same, was exhausted when I was doing that and thought I was seeing things

Lmao kill me
Fyi, "cynate" and "cyanate" are both acceptable spellings. It's like aluminum and aluminium
Genuinely never heard about that. Source?
Can someone find me the procedure he used?
Why not just use his procedure and write it down? Or do you need it for a specific reason?
I used scihub to access it but here's the link https://pubs.rsc.org/en/content/articlelanding/1897/ct/ct8977100607#!divAbstract
You think that new England snow is cold, try the Canadian stuff.
I'm not trying to liquefy Helium, so I think I'll pass.

Got your seal of approval, thank the lord

Bruh that's eBay shid right there.

Yes.
no yellow chem bad
Yellow chem very good. Cowards think yellow chem bad. Jk 😂😉
Sike it's opposite day.
You played yourself.
You heard it here folks! No yellow chemistry is bad!
Very nice, but the title is herecy.
No
"Is yellow chem bad?"
I say, and you reply:
Definetly not a Comment - 2021-03-15
-Editing
-Dank memery and Jokes
-Rhondanide in a Rhondanide video (again)
-toxic but colorful metal compounds
-flexing more with Sigma than with his new car
Our boy has officially returned!
Also: EnF is away: Time to post Yellow Chem!

"Rhondanide", "Thiocynate"... Can no one spell this chemical's name correctly? ^^

@piranha031091 seems not lol
