The processing of liquid chlorinated hydrocarbon residues, which may contain solids and which form viscous to solid deposits during the separation of readily boiling components, into (1) distillable organic components, (2) hydrogen chloride, and (3) solid matter with a low chlorine content, is improved by gently concentrating the residues in a first step and, in a second step, decomposing the residues at temperatures of about 200 DEG -400 DEG C., preferably 270 DEG -330 DEG C., with a continuous separation of the vapor phase components from the solid components. |
