| 摘要 |
A process is disclosed for producing CF3CH2F from CF3CHClF by catalytic chlorination of CF3CHClF to CF3CCl2F at elevated temperature, and reaction of CF3CCl2F with H2 in the presence of a carbon-supported precious metal catalyst at a temperature of from about 100 DEG C. to 250 DEG C. Suitable catalysts for the chlorination include carbon catalysts and catalysts wherein halides of certain metals (La, Zn, Cu, Cr, Ru, Rh, and/or Pt) are supported on carbon.
