Abstract
Production of vinylidene fluoride by reacting dichlorodifluoromethane with methane in a heated reactor element containing a non-metallic packing material which is stable at the operating temperatures of the process, wherein the reactor element subjects the gaseous reactants to a temperature within the range 500.degree. C. to 1200.degree. C. and wherein the calculated residence time for the gaseous reactants in the reaction zone is within the range of from 0.1 to 10.0 seconds.
