实验过程

Mixtures of 2,2-dichloro-1,1,1,2-tetrafluoroethane (CFC-114a), dichlorodifluoromethane (CFC-12) and hydrogen were fed to a reactor operated at several temperatures for 92 hours. For a 10.5 hour period at 600° C., at an average time in synthesis of 38 hours, with liquid feed rates of 11.9 mL/hr of CFC-114a and 1.2 mL/hr of CFC-12 and a hydrogen feed rate of 500 cc/min (1 atm. and room temperature basis); a molar ratio of (CFC-114a+CFC-12):H2 equal to 1:11 was provided, and the organic component of the reactor effluent contained an average (area percent) of 0.97% difluoromethane (HFC-32), 1.57% chlorodifluoromethane (FCFC-22), and 0.25% CFC-12, as well as 37.7% HFC-134A, 56.0% HCFC-124 and 2.8% CFC-114a.
