METHODS FOR CONVERTING INTERMEDIATES IN PROCESSES FOR PRODUCING trans-1,2-DIFLUOROETHYLENE (HFO-1132E)

Abstract: in a first step reaction for producing 1,1,2-trifluoroethane (hfc-143) from 1,1,2-trichloro-1,2,2-trifluoroethane (cfc-113) as part of an overall method for production of trans-1,2-difluoroethylene (hfo-1132e), several intermediates and/or byproducts are formed, some of which may be considered desired and others undesired. the overall reaction methods and/or specific reactions conditions for producing 1,1,2-trifluoroethane (hfc-143) from 1,1,2-trichloro-1,2,2-trifluoroethane (cfc-113) may be selectively tailored to usefully convert desired intermediates to the desired product 1,1,2-trifluoroethane (hfc-143) and/or minimize the formation of undesired byproducts.
