ABSTRACT:
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 comprising providing a solution containing 1,1-dichloro-1-fluoroethane and vinylidene chloride; and contacting said solution with chlorine and an alumina catalyst to effect chlorination of said vinylidene chloride to produce a chlorinated compound having a boiling point different than said 1,1 dichloro-1-fluoroethane.
