Abstract

PURPOSE: To produce vinylidene chloride which is a raw material of polymers, in high yield under mild conditions and through simple operations, by the dehydrochlorination of easily available 1, 1, 1-trichloroethane, in the presence of a chromium compound.
CONSTITUTION: Vinylidene chloride is produced by the contact of 1, 1, 1-trichloroethane with an inorganic chromium(III) compound at a temperature of about 80W350°C. Chromium(III) oxide, hydroxide, halide, etc. are preferable as the inorganic chromium(III) compound, and these are desirably allowed to stand in an atmosphere of HF under an appropriate temperature and pressure for 1W5 hr. to stabilize the catalytic activity. Reaction time is usually 0.5W30 sec.
