The dehydrochlorination of 1,1,2,3,3-pentachloropropane to produce 1,2,3,3-tetrachloropropene is conducted using aqueous alkali metal hydroxide in the substantial absence of added ethanol. n The 1,2,3,3-tetrachloropropene is recovered from the reaction mixture in the substantial absence of added ether. The preferred methods of recovery are steam distillation and flash distillation. |
