实验过程

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 11 hour period at 470° C., at an average time in synthesis of 67 hours, with a feed molar ratio of hydrogen to CFC-114/114a isomers of 2.1:1, and a liquid feed rate of 2.0 mL/hr of the combined 2,2-dichloro and the 1,2-dichloro isomers, the average conversion of the 2,2-dichloro isomer was 86% and the average conversion of the 1,2-dichloro isomer was 48%. The reactor effluent contained in addition to HCl and hydrogen, 2.3% HFC-134, 10.2% HCFC-124a and 13.9% CFC-114, as well as 0.4% HFC-134a, 1.6% HCFC-124 and 0.3% CFC-114a.
