Reaktionsschritte

Various mixtures of 2,2-dichloro-1,1,1,2-tetrafluoroethane (CFC-114a) and 1,2-dichloro-1,1,2,2-tetrafluoroethane (CFC-114) and hydrogen were fed to the reactor for a period of 170 hours. For an 11 hour period at 600° C., at an average time in synthesis of 50 hours, with a feed molar ratio of hydrogen to CFC-114/114a isomers of 11:1, and a liquid feed rate of 13.2 mL/hr of an equal mixture of the 2,2-dichloro and the 1,2-dichloro isomers, the average conversion of the 2,2-dichloro isomer was 98% and the average conversion of the 1,2-dichloro isomer was 80%. The reactor effluent contained in addition to HCl and H2 1.36% HFC-134, 0.67% HCFC-124a and 0.68% CFC-114, as well as 1.34% HFC-134a, 2.04% HCFC-124 and 0.06% CFC-114a.
