Abstract
Disclosed is a method of chlorinating vinylidene chloride contained in a solution 1,1 -dichloro-1-fluoroethane to provide a chlorinated compound having a boiling point different from the 1,1-dichloro-1-fluoroethane to permit separation therefrom. The method comprises providing a solution containing 1,1-dichloro-1-fluoroethane and vinylidene chloride; introducing chlorine to the solution; and contacting the chlorine containing solution with a metal oxide to effect chlorination of the vinylidene chloride to produce one of 1,1,1,2-tetrachloroethane, trichloroethylene and pentachloroethane.
