| titleOfInvention | Treatment of aliphatic chlorinated hydrocarbons with hydrazines or diamines |
| abstract | 1299553 Purification of halohydrocarbons UDDEHOLMS AB 19 April 1971 [16 March 1970] 23101/71 Heading C2C Oxidising impurities are removed from chlorohydrocarbons by treatment with hydrazine or a water-soluble saturated aliphatic hydrazine or diamine of formula C n H 2n+4 N 2 , in which n is 1 to 6. Hydrazines and diamines specified are hydrazine hydrate, dimethyl hydrazine, ethylene diamine and hexamethylene diamine. Chlorohydrocarbons specified are trichloroethylene, perchloroethylene, and an oxychlorination reaction product comprising mainly dichloroethylene, trichloroethylene and perchloroethylene. The chlorohydrocarbon may be subsequently treated by one or more of heating, washing with water, passage through activated carbon, distillation, drying, e.g. with calcium chloride, silica gel, alumina or potassium carbonate, and stabilisation, e.g. with thymol, triethylamine, di - isopropylamine; 3 - methyl 1-penty-3-nol, 2,6-di.t-butyl phenol or 4-methyl morpholine. |
