Abstract
An object is to provide an efficient method for producing HFC-143 or HFO-1132. Provided as a means for solution is a method for producing 1,1,2-trifluoroethane (HFC-143), comprising subjecting 1,1,2-trifluoroethylene to a reduction reaction with a reducing agent in the presence of a catalyst to obtain HFC-143.
Claims4
A method for producing 1,1,2-trifluoroethane (HFC-143), comprising a step of subjecting 1,1,2-trifluoroethylene to a reduction reaction with a reducing agent at a temperature of 200 to 300° C. to obtain HFC-143.
(canceled)
A method for producing 1,2-difluoroethylene (HFO-1132), comprising:
- step 1 of subjecting 1,1,2-trifluoroethylene to a reduction reaction with a reducing agent at a temperature of 200 to 300° C. to obtain 1,1,2-trifluoroethane (HFC-143);
- and
- step 2 of subjecting HFC-143 obtained in step 1 to dehydrofluorination to obtain HFO-1132.
