Chemguy Posted December 14, 2006 Share Posted December 14, 2006 Well recently I have been interested in acyl chlorides, (a HE?) but that is not what this is about. I have searched about methods to make thionyl chloride SOCl2 without much success. I have found a few, but they require PCl3 and SCl2. Which I cannot make, unfortunately. If it is possible to bypass using thionyl chloride for this then please tell me, help would be appreciated. Link to comment Share on other sites More sharing options...
Mumbles Posted December 14, 2006 Share Posted December 14, 2006 I know of no bypass without SCl2 or PCl3. Generally for the homebrew scientist the reaction is SCl2 + SO3 ---> SOCl2 + SO2. Fun stuff I know. Making SCl2 is not all that hard, but I could see it as being something you probably wouldn't want to attempt. Link to comment Share on other sites More sharing options...
Chemguy Posted December 14, 2006 Author Share Posted December 14, 2006 You're right, chlorine and molten sulfur = Bad. Also SO3 is hard to make. I think I remember an equation S2Cl2 + Cl2 + SO2 --SOCl2 + SCl2. My book on chemistry describes SCl2 as an evil smelling red liquid that when mixed with C2H4 makes mustard gas! Not encouraging.

Mumbles Posted December 15, 2006 Share Posted December 15, 2006 Hmmmmm, I thought S2Cl2 was red, and SCl2 was yellow. Perhaps I'm getting a bit rusty. I personally wouldn't be too worried about making it. I have the apparatus to do it safely though. Link to comment Share on other sites More sharing options...
Chemguy Posted December 16, 2006 Author Share Posted December 16, 2006 Thankyou, you have been really helpfull! , I would like to try this, I have the equipment to, (just) however wouldn't the molten sulfur be impossible to get out of the flask, I have had troubles with this before when attempting small amounts of CS2.

Mumbles Posted December 16, 2006 Share Posted December 16, 2006 Not if you react it all. Cl2 will react with it quickly. I don't think there will be a huge problem with it staying in there. Hot toluene can also be used to free it. Link to comment Share on other sites More sharing options...
