Conversion of chlorofluororopanes and chlorofluropropenes to more desirable fluoropropanes and fluororopenes

摘要

A process is provided comprising contacting and reacting the compound CF3CF2CHXCl, wherein X is H or Cl, or the compound CF3CF═CXCl, wherein X is H or Cl, with hydrogen in the presence of a catalyst consisting essentially of Cu, Ru, Cu—Pd, Ni—Cu, and Ni—Pd, to obtain as a result thereof reaction product comprising hydrofluoropropenes or intermediates convertible to said hydrofluoropropenes, notably CF3CF═CH2 and CF3CH═CHF.

1. A process comprising contacting and reacting the compound CF3CF2CHCl2, or the compound CF3CF═CXCl, wherein X is H or Cl, with hydrogen in the presence of a catalyst consisting essentially of Cu, Ru, Cu—Pd, Ni—Cu, or Ni—Pd, to obtain as a result thereof a reaction product comprising the compound CF3CF═CH2 and at least one of the compounds CF3CF═CHCl or CF3CF2CH2Cl, wherein no detectable CF3CH═CH2 is found in said reaction product, and wherein the CF3CF═CHCl is converted to the reaction product comprising the compound CF3CF═CH2 by hydrogenation in the presence of a catalyst.
