Versuchsvorschrift

A mixture containing about 8% 2,2-dichloro-1,1,1,2-tetrafluoroethane (CFC-114a) and about 92% 1,2-dichloro-1,1,2,2-tetrafluoroethane (CFC-114) and hydrogen were fed to the reactor for a period of 477 hours. For an 3 hour period at 560° C., at an average time in synthesis of 275 hours, with a feed molar ratio of hydrogen to CFC-114/114a isomers of 2.2:1, and a liquid feed rate of 1.0 mL/hr of the combined 2,2-dichloro and the 1,2-dichloro isomers, the average conversion of the 2,2-dichloro isomer was 96% and the average conversion of the 1,2-dichloro isomer was 92%. The reactor effluent contained in addition to HCl and hydrogen, 17.4% HFC-134, 4.5% HCFC-124a and 2.0% CFC-114, as well as 2.0% HFC-134a, 0.5% HCFC-124 and 0.1% CFC-114a.
