<p>A process for producing 1,1,1,2,3,3-hexafluoropropane which comprises dechlorofluorinating 1,1,2,2-pentafluoro-3,3- dichloropropane and/or 1,1,2,2,3-pentafluoro-1,3-dichloropropane with hydrogen in the presence of a metal oxide catalyst, and fluorinating the resultant olefin in the presence of a catalyst. This process serves to produce readily at a low cost 1,1,1,2,3,3- hexafluoropropane, which is useful as a working fluid and is capable of environmental protection, and an intermediate for the preparation thereof.</p> |
