Abstract
Official abstract text for this publication.
A process is disclosed for making CF 3 CF═CHF. The process involves reacting CF 3 CClFCCl 2 F with H 2 in a reaction zone in the presence of a catalyst to produce a product mixture comprising CF 3 CF═CHF. The catalyst has a catalytically effective amount of palladium supported on a support selected from the group consisting of alumina, fluorided alumina, aluminum fluoride and mixtures thereof and the mole ratio of H 2 to CF 3 CClFCCl 2 F fed to the reaction zone is between about 1:1 and about 5:1. Also disclosed are azeotropic compositions of CF 3 CClFCCl 2 F and HF and azeotropic composition of CF 3 CHFCH 2 F and HF.

What is claimed is: 1. A composition comprising HFO-1225ye, CFO-1215yb, and CFO-1234yf, and optionally one or more of HFO-1243zf, HFC-245eb, HCFC-244eb, HCFC-226ea, HCFC-235bb and HFC-263fb. 2. The composition of claim 1 wherein the member comprises HCFC-226ea. 3. The composition of claim 1 wherein the member comprises HFC-245eb. 4. The composition of any of claim 1 , 2 or 3 , wherein the HFO-1225ye comprises E-HFO-1225ye and Z-HFO-1225ye. 5. The composition of claim 4 wherein the E-HFO-1225ye is present in an amount greater than Z-HFO-1225ye. 6. The composition of claim 4 wherein the E-HFO-1225ye is present in an amount less than Z-HFO-1225ye. 7. A composition comprising Z-HFO-1225ye, CFO-1215yb, and HFO-1234yf, and optionally one or more of E-HFO-1225ye, HFC-263fb, HFO-1243zf, HFC-254eb, HCFC-226ea and HCFC-235bb. 8. A process comprising distilling the composition of any of claims 1 - 3 and isolating HFO-1225ye. 9. A process comprising distilling the composition of claim 4 and isolating E-HFO-1225ye and Z-HFO-1225ye.
