Abstract
The present invention relates, at least in part, to a process for making chlorotrifluoroethylene (CFO-1113) from 1,2-dichloro-1,1,2-trifluoroethane (HCFC-123a). In certain aspects, the process includes dehydrochlorinating 1,2-dichloro-1,1,2-trifluoroethane (HCFC-123a) in the presence of a catalyst selected from the group consisting of (i) one or more metal halides; (ii) one or more halogenated metal oxides; (iii) one or more zero-valent metals or metal alloys; (iv) combinations thereof.

A process for producing chlorotrifluoroethylene (CFO-113) comprising:
- dehydrochlorinating 1,2-dichloro-1,1,2-trifluoroethane (HCFC-123a) in the presence of a catalyst selected from the group consisting of (i) one or more metal halides;
- (ii) one or more halogenated metal oxides;
- (iii) one or more zero-valent metals or metal alloys;
- and (iv) combinations thereof to produce a reaction product comprising CFO-1113, wherein said catalyst comprises at least a catalyst (ii), wherein said catalyst (ii) comprises fluorinated MgO;
- and from about 5.0 wt. % to about 50 wt % based on the total weight of the catalyst of one or more of a fluorinated Cs2O, a fluorinated Li2O, a fluorinated Na2O, and/or a fluorinated K2O.
