PRODUCTION OF TETRAFLUOROETHYLENE AND HEXAFLUOROPROPYLENE

摘要

QM 34268 Process for the production of tetrafluoroethylene and hexafluoropropylene which allows these monomers to be formed in very high combined selectivity, which process comprises the pyrolysis of chlorodifluoromethane, optionally using gaseous diluent, wherein the pyrolysis is effected under substantially isothermal and uniform conditions, the reaction temperature is within the range 750.degree.C-980.degree.C (preferably 800.degree.C-980.degree.C), and the gaseous residence time is within the range 1 to 50 milliseconds. A fluid phase electromagnetic induction reactor suitable for use in effecting the process is described.
