Thiophosgene. Sulfur analogue of phosgene

Thiophosgene is a suflur analogue of phosgene. It's an orange-red liquid with strong smell! And this reagent is the highlight of today's video!

​@@MinecrafterRedstoner I once synthesized ethyl carbamate, and unfortunately decided to evaporate inton low heat hot plate. Unfortunately I disrupted from this process and forgot few grams ethylcarbamate on hotplate. My garage became a little Bhopal when I return to experiment. I didn't knew, that one of ethylcarbamate thermal decomposition products is methyl isocyanate (MIC), and learn it in hard way! Thankfully it was only few grams, that yield less then 1 gram MIC, but even that was horrible!

The "kitty litter" in the Acros package is vermiculite, a form of expanded mica. It is very absorbent, has low reactivity and high heat tolerance, so it is often used for packaging reactive and/or pyrophoric chemicals.

@@dielaughing73Not on purpose. Sometimes leftover refrigerant trapped in the oil and when you take a torch to it, the refrigerant burns to phosgene. Only does it with older refrigerants. The new stuff is gnarly too though. It was mostly out of carelessness. It's been years.

"It's an orange-red liquid with strong smell" he said. Well, I was actualy working with it, and you know... This liquid have by far the worst, soulriping smell I've ever deal with. Second worst Bu3P, PH3 or PhCH2COCl isn't even close to that (may be concentrated tech PH3 a bit). Thiophosgene smels like PCl3 or COCl2, BUT... When you smell PCl3 or COCl2 you think "Oh, this thing could kill me". When you smell thiophosgene you think "Oh f*ck, this thing is for shure urge to kill me. Run. Now!" And that's the only thought that completely occupies your mind at this moment.

The "special absorbent powder that resembles cats toilets" is expanded vermiculite. I don't know about the rest of the world, but in USA that stuff is well known to be contaminated with asbestos.

[@davidcoghill8612]

As far as I've been able to find out, this was vermiculite that came from a specific mine that closed in the 90s. Any new vermiculite is safe, it's just a concern for example if you find some vermiculate insulation in an old house.

[@arthurmorgan8966]

I might be remembering the name wrong, but I was doing engineering work for a large scale grain silo, tablets of phosgene was used as fumigation agent to kill the bugs and whatnot. Nasty stuff. There was a small spill in a semi-confined area, unaware workers inhaled a little (no mask) and got sick. Reason? The lazy bastard who was supposed to go on top of the silo to put some amount every once in a while while conveyors are filling it, decided to go and dump into conveyors before the grain elevators. There was an overload, elevators stalled, workers had to open the lids to empty it with shovels. To this day I hate that sob.

[@joeylawn36111]

May have been instead something like aluminum phosphide, a solid, which decomposes via moisture into a similar-named gas called Phosphine (PH3). Phosgene (COCl2) is a gas itself, so it would not be in tablet form. Phosphine and phosphine releasers are used in fumigating grain.

[@reinisaugustins8555]

You were using phosphine (PH3), also known as hydrogen phosphide or phosphorus trihydride, not phosgene (COCl2), also known as carbonic chloroanhydride or chloroformaldehyde. These are completely different gases. Phosgene is not used as a fumigant, but phosphine, although controversial due to many poisoning deaths, is a popular fumigant, especially for grain.

[@louistournas120]

thiohypochlorite? Is that a Cl connected to a S and it has a minus charge on the S? I guess trichloromethyl is CCl3 and there is a bond between the C and the S from ClS. IUPAC names are easier to understand.
