Abstract

Chlorinated hydrocarbons are almost totally recovered from the reaction gases obtd. by the oxychlorination of ethylenically unsatd. hydrocarbons of 2-4C, partic ethylene, by HCl and O2, by cooling the gas current to form a 1st mixt. of liq. and vapour, in which the liq. fraction contains practically all the chlorinated hydrocarbon and water, sepg. the vapour phase from the liq. and cooling the vapour phase further to -30 degrees to -10 degrees C, after adding HCl gas, to form a second mixt. of liq. and vapour, of which the liq. contains a small residual amt. of chlorinated hydrocarbon. The two liq. phases are mixed. The liq. phase consists of two parts an aq. and an org. phase. The org. phase consists of the desired chlorinated hydrocarbon. An arrangement for operating continuously is described. Used for making ethylene dichloride.
