ABSTRACT:
A catalyic process is disclosed for producing CCl.sub.3 CF.sub.3 from CHCl.sub.2 CF.sub.3, CH.sub.2 ClCF.sub.3 and/or CH.sub.3 CF.sub.3 by chlorination at elevated temperature. Suitable catalysts for the process include carbon catalysts and catalysts wherein halides of certain metals (Zn, Cu, Cr, Ru, Rh, and/or Pt) are supported on carbon.
