Abstract

A process for the work-up of chlorination residues by dissolving the same at temperatures between 100.degree. and 180.degree. C. in chlorine- and oxygen-containing hydrocarbons having a ratio by weight of hydrogen to chlorine of 0.028-0.06:1, a ratio by weight of oxygen:carbon of 0.0038-0.0089:1, and an atomic ratio of carbon:hydrogen of 1:1.1-1.9 and/or in hydrocarbons, boiling between 160.degree. and 380.degree. C. at one bar abs. and having an atomic ratio carbon:hydrogen of 1:1.85-2.0 so as to obtain a liquid preparation having a ratio by weight of hydrogen:chlorine of 0.028-0.05:1.
