Abstract
A novel method for manufacturing 1,1,1,3,3,3-hexachloropropane. Tetrachloromethane is reacted with 1,1-dichloroethene in the presence of a catalyst comprising copper and a solvent selected from a C3 to a C5 alkanenitrile. The 1,1,1,3,3,3-hexachloropropane can be separated from the reaction by-products, unconsumed reactants and catalyst and solvent, which components can be recovered and recycled back to the reactor.
