摘要: An improved process is described for producing chlorotrifluoroethylene, a useful monomer for making high strength chlorofluoropolymers, comprising passing a mixture of 1,1,2-trichloro-1,2,2-trifluoroethane, ethylene, hydrogen chloride and elemental oxygen in the vapor phase, at a temperature from about 350.degree. to 525.degree. C., over a catalyst consisting essentially of a mixture of copper chloride and an alkali metal chloride, preferably a eutectic mixture, occluded in a molecular sieve, having an average pore size diameter in the range of about 5 to 11 angstroms.A new catalyst composition is also described, useful in oxyhydrochlorination processes conducted at temperatures above 350.degree. C., consisting essentially of a mixture of copper chloride and an alkali metal chloride, preferably a eutectic mixture, occluded in a molecular sieve, having an average pore size diameter in the range of about 5 to 11 angstroms.

摘要: Hydrogen contamination of chlorine-containing gas, such as the chlorine gas from the electrolytic chlorine/caustic process and especially the tail gas from the chlorine liquefaction operation, is eliminated by reaction of the hydrogen directly in the gas mixture at elevated temperature in the presence of a catalyst, to effect combination of the hydrogen with chlorine to form hydrogen chloride, followed by scrubbing of the hydrogen chloride from the gas.
