摘要:
A dehydrochlorination process is disclosed. The process involves contacting RfCHClCH2Cl with a catalyst in a reaction zone to produce a product mixture comprising RfCCl═CH2, wherein said catalyst comprises MY supported on carbon, and wherein Rf is a perfluorinated alkyl group, M=K, Na or Cs, and Y=F, Cl or Br.
