Appeal No. 2001-2396
Application 09/286,150
THE INVENTION
The appellants claim a method for making 1,1,1,3,3-
pentafluoropropene by reacting 2,2-dichloro-1,1,1,3,3,3-
hexafluoropropane with hydrogen in the presence of a metal-
containing catalyst on a carbon support, and claim a method
wherein 1,1,1,3,3-pentafluoropropene is produced by this method
and is recovered and reacted with hydrogen in the presence of a
metal-containing catalyst on a carbon support to produce
1,1,1,3,3-pentafluoropropane. Claim 1 is illustrative:
1. A method for the production of 1,1,1,3,3-
pentafluoropropene which comprises contacting 2,2-dichloro-
1,1,1,3,3,3-hexafluoropropane with hydrogen in the presence of a
metal-containing catalyst carried by a carbon support, at a
temperature in the range of about 300EC to about 800EC, and
recovering the 1,1,1,3,3-pentafluoropropene from the resulting
reaction product, wherein the metal-containing catalyst carried
by a carbon support is selected from the group consisting of a
metal, metal halide, metal oxide, metal oxyhalide and
combinations thereof, wherein the metal of the catalyst is
selected from the group consisting of Fe, Cu, Ni and Cr.
