Dichloroacetyl chloride use and synthesis
Chemical properties Colorless and irritating liquid. It is miscible with ether.
Uses for organic synthesis and pesticides, pharmaceutical intermediates
Use as an organic synthesis intermediate
Use It is used in the synthesis of vinyl insecticides. It is also used in wool felting finishing, bleaching, decolorization, preservation, sterilization, disinfection and so on.
Production methods A variety of process routes can be employed in the preparation process. The reaction of dichloroacetic acid with chlorosulfonic acid, the reaction of chloroform with carbon monoxide under anhydrous aluminum trichloride, the reaction of dichloroacetic acid with phosgene in dimethylformamide, and the oxidation with trichloroethylene, etc. This product. Trichloroethylene and azobisisobutyronitrile (catalyst) are heated to 100 ° C, oxygen is introduced, and the reaction is carried out under a pressure of 0.6 MPa. The temperature of the oil bath is maintained at 110 ° C for 10 hours, and the product dichloroethylene is distilled off under normal pressure. Acid chloride. The reaction by-product trichloroethylene oxide can also be converted into dichloroacetyl chloride by reaction with an amine compound such as methylamine, triethylamine or pyridine.
