Abstract
Olefinic halides are produced by catalytic dehydrohalogenation of the corresponding saturated halide by direct contact thereof with a melt containing a multivalent metal halide in its higher and lower valence state. In particular, 1,2-dichloroethane is dehydrochlorinated to vinyl chloride by contacting thereof with a molten salt mixture of cuprous and cupric chloride at high per pass conversion and high vinyl chloride selectivity.
