Research progress in the synthesis of 1,1,2-trichloroethane

1,1,2-trichloroethane is very important in the chemical industry and can be used as a solvent, extract, insecticide and anesthetic in the medical field, as well as a raw material for the preparation of correction fluids and for the production of 1,1-dichloroethane. The paper briefly discusses the synthesis of 1,1,2-trichloroethane.At present, the methods of producing TCE are vinyl chloride, tower synthesis,1,2-dichloroethane reaction distillation, olefin mixed waste gas, azeotropic distillation.
