Abstract:
A process for the manufacture of vinyl fluoride from 1,1-difluoroethane which comprises contacting said 1,1-difluoroethane at an elevated temperature with a catalyst containing at least one divalent Group II metal compound, characterized by:contacting said 1,1-difluoroethane at a temperature of from about 200.degree. C. to 400.degree. C. with a catalyst containing (a) at least one compound selected from the oxides, fluorides and oxyfluorides of magnesium, zinc and mixtures of magnesium and zinc, and optionally (b) at least one compound selected from the oxides, fluorides and oxyfluorides of aluminum; provided that the atomic ratio of any metals other than magnesium and zinc, in total, to the total of magnesium and zinc in said catalyst is about 1:4, or less.
