| Use | dichloroacetyl chloride is an agent with antitumor and anticancer activity useful in the synthesis of substituted benzothiazoles. used in organic synthesis and pesticides, pharmaceutical intermediates used as intermediates in organic synthesis used in the synthesis of vinyl pesticides, also used in wool felting finishing, bleaching, decolorization, preservation, sterilization, Disinfection, etc. |
| production method | a variety of process routes can be used in the preparation method. The reaction of dichloroacetic acid with chlorosulfonic acid, the reaction of chloroform with carbon monoxide catalyzed by anhydrous aluminum trichloride, the reaction of dichloroacetic acid with phosgene in dimethylformamide, and the oxidation of trichloroethylene can be obtained. Trichloroethylene and azobisisobutyronitrile (catalyst) were heated to 100 ° C., oxygen was introduced, and the reaction was carried out under 0.6MPa pressure. The temperature of the oil bath was maintained at 110 ° C., and the reaction was carried out for 10 hours. The by-product of the reaction, trichloroethylene oxide, can also be converted into dichloroacetyl chloride by reacting with amine compounds such as methylamine, triethylamine and pyridine. |
