Patent number: 8133406Abstract: A process is disclosed for making CF3CF?CH2 or mixtures thereof with CHF2CF?CHF. This process involves (a) reacting CHCl2CF2CF3, and optionally CHClFCF2CClF2, with H2 in the presence of a catalytically effective amount of a hydrogenation catalyst to form CH3CF2CF3 and, when CHClFCF2CClF2 is present, CH2FCF2CHF2; (b) dehydrofluorinating CH3CF2CF3, and optionally any CH2FCF2CHF2, from (a) to form a product mixture including CF3CF?CH2 and, if CH2FCF2CHF2 is present, CHF2CF?CHF; and optionally (c) recovering CF3CF?CH2, or a mixture thereof with CHF2CF?CHF from the product mixture formed in (b) and/or (d) separating at least a portion of any CHF2CF?CHF in the product mixture formed in (b) from the CF3CF?CH2 in the product mixture formed in (b).Type: GrantFiled: October 31, 2007Date of Patent: March 13, 2012Assignee: E.I. du Pont de Nemours and CompanyInventors: Mario Joseph Nappa, Velliyur Nott Mallikarjuna Rao, Allen Capron Sievert
