Patent ID: 7214294

Claim:
A process for removing water from 1,1,1,3,3-pentafluoropropane which process comprises distilling a mixture of 1,1,1,3,3-pentafluoropropane and water containing 1,1,1,3,3-pentafluoropropane in excess of the concentration necessary for the mixture of 1,1,1,3,3-pentafluoropropane and water to exist as an azeotrope or azeotrope-like composition to separate an azeotrope or azeotrope-like composition consisting essentially of 1,1,1,3,3-pentafluoropropane and water from the 1,1,1,3,3-pentafluoropropane present in excess of die concentration necessary for the mixture of 1,1,1,3,3-pentafluoropropane and water to exist as an azeotrope or azeotrope-like composition.
