Summary
-
1.
The thermal transformations of trichloroethylene at high pressures we investigated. Under the conditions studied the main products of the process were 1,1,2,4,4-pentachloro-l,3-butadiene and, in a smaller amount, 1,1,1,3-tetrachloroethane.
-
2.
The thermal transformations of trichloroethylene are greatly accelerated by pressure. At a pressure of 25,000 atm reaction at 190° becomes self-accelerating and leads to partial carbonization of the material. The temperature at which self-acceleration of the reaction occurs rises as the pressure is lowered.
-
3.
A possible radical-chain scheme is discussed for the dimerization of trichloroethylene under the conditions studied.
