Abstract

PURPOSE: To prepare vinylidene chloride in high yield, by dehydrochlorinating 1,1,2-trichloroethane in vapor phase at a specific temperature in the presence of a specific amount of steam and a specific catalyst.
CONSTITUTION: Vinylidene chloride is prepared in high yield and in remarkably high selectivity with exceedingly suppressed lowering of the catalyst activity, by the vapor-phase dehydrochlorination of 1,1,2-trichloroethane at 250W500°C, preferably at 300W450°C in the presence of 0.1W10mol, preferably of 0.5W5mol on the basis of 1mol of the raw material of steam, and a catalyst provided by impregnating a silica carrier with a halide of anelement selected from cesium, rubidium and potassium.
