1,1-Dichloroethane - Uses and synthesis methods
Production method
Industrially, vinyl chloride is obtained by liquid phase reaction of 1, 1-dichloroethane with hydrogen chloride under the catalysis of aluminum chloride, ferric chloride or zinc chloride. In the production of 1, 2-dichloroethane from ethylene chlorination, a small amount of 1, 1-dichloroethane is also produced by-product.
