Abstract

Procedure for the recovery of residual heavy chlorinated hydrocarbon mixtures, derived from the manufacture of chlorinated solvents in C1 and/or C2, characterized in that heavy residues and molecular chlorine are introduced into a chlorination zone in the vapor phase at a temperature comprised between 400º and 600ºC, the effluent is then subjected to a separation by distillation of carbon tetrachloride and perchlorethylene resulting in recovered products, and the residue from this distillation and molecular chlorine are passed to a homogeneous zone of chlorination in the liquid phase where the temperature is from 100º to 200ºC, under atmospheric pressure and where chlorination is carried out in the presence of 15 to 1800 parts per million by weight of ferric chloride.
