Talk:Dichloroacetylene

Decomposition
Does dichloroacetylene decompose directly into the elements during explosion, or does it form CCl4 and other thermodynamically more stable chlorocarbons? Or does it only explode if it is in contact with air? --79.243.235.94 (talk) 20:49, 5 September 2013 (UTC)


 * By now I haven't found any specific information on that. My first guess would be 2 C2Cl2 -> 2 C + C2Cl4 because that could easily explain why it is much more stable when diluted in an inert gas or solvent (because this would be a two-molecule reaction, and dilution reduces the chance for two C2Cl2 molecules to meet). For the reaction C2Cl2 -> 2 C + Cl2 it doesn't necessarily need the interaction of two molecules. But this is mere personal speculation.
 * If I compare C2Cl2 to its much better known analogue acetylene my guess may be wrong after all. Because acetylene is also prone to self-decomposition when concentrated but not when diluted, and its primary decomposition route seems to be C2H2 -> 2 C + H2.
 * It could also be both - chlorine being produced first but then adding across the triple bond of a second C2Cl2 molecule when chlorine partial pressure is high enough.
 * Anyways, I can't say what exactly happens without a reliable source. And as said, I haven't found one yet. --2003:E7:772E:5A18:8146:4373:7DCC:18EA (talk) 04:46, 13 January 2021 (UTC)

pyrolysis of difluoromaleic anhydride
Shouldn't that be dichloromaleic anhydride?

That would make more sense in terms of stoichiometry. --2003:E7:772E:5A18:8146:4373:7DCC:18EA (talk) 05:00, 13 January 2021 (UTC)
