1. A dehydrochlorination process comprising contacting RfCHClCH2Cl with a carbon catalyst in a reaction zone to produce a product mixture comprising RfCCl═CH2, wherein Rf is a perfluorinated alkyl group, wherein the temperature in the reaction zone ranges from about 325° C. to about 500° C. and wherein the product selectivity to Rf CCl═CH2 is at least 90 mole %. |
