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.
Claims7
A process for the work-up of chlorination residues, comprising the steps of:
- obtaining a preparation containing chlorination residues composed substantially of perchlorinated compounds having a chemical composition represented approximately by the summation formula
- C.sub.5-6 Cl.sub.5.8-6.0
- and
- dissolving said chlorination residues at temperatures between 100.degree. and 180.degree. C. in a solvent selected from the group consisting of hydrocarbons containing chlorine and oxygen, in which the ratio of hydrogen:chlorine is 0.028-0.06:1 by weight, the ratio of oxygen:carbon is between 0.0038-0.0089:1 by weight, the atomic ration of carbon to hydrogen is from 1:1.1-1.9, hydrocarbons having a boiling point between 160.degree. and 180.degree. C. at one bar abs. in which the atomic ratio of carbon:hydrogen is between 1:1.85-2 and a combination of said hydrocarbons, wherein the amounts of components are so chosen that a liquid preparation is obtained having a weight ratio of hydrogen:chlorine from 0.028 to 0.05:1.
