A process for the manufacture of CF3CF=CF2is disclosed. The process involves contacting 2,3-dichloro-1,1,1,2,3,3-hexafluoropropane with at least 0.1 mole of hydrogen in a reaction vessel of titanium, nickel or iron or their alloys, which is either empty or packed with particles or formed shapes of t
A process for the manufacture of CF3CF=CF2is disclosed. The process involves contacting 2,3-dichloro-1,1,1,2,3,3-hexafluoropropane with at least 0.1 mole of hydrogen in a reaction vessel of titanium, nickel or iron or their alloys, which is either empty or packed with particles or formed shapes of titanium, nickel or iron or their alloys, at a temperature within the range of from about 350° C. to about 600° C. and for a time sufficient to produce hexafluoropropene. Also disclosed are compositions which comprise hydrogen fluoride in combination with an effective amount of CClF2CClFCF3to form an azeotrope or azeotrope-like composition with hydrogen fluoride. The compositions contain from about 8.7 to 33.6 mole percent CClF2CClFCF3.
