1. Hexachloroethane by hexachloroethane method is reacted with hydrogen fluoride in the presence of antimony pentachloride as a catalyst, and the reaction product is subjected to alkali washing, water washing, fractionation and purification to obtain a finished product.
2. Tetrachloroethylene method
This method is an improvement on the production of hexachloroethane. The process is simplified, the yield is high, and the labor protection conditions are improved.
mainly used as Polychlorotrifluoroethylene monomer, also used as refrigerant, cleaning agent, dry cleaning agent, foaming agent, fire extinguishing agent and solvent.
