Abstract
Liquid ethylene dichloride containing chloral as a contaminant is purified by contacting the impure ethylene dichloride with an aqueous solution of an alkali metal hydroxide or ammonium hydroxide, maintaining the temperature in the range 50-150 DEG F. during contact and separating the ethylene dichloride, e.g. by distillation optionally after a dehydration step. The process is suitable for treating the product obtained by the oxychlorination of ethylene.
