More Information
Summary:Provided are azeotropic and azeotrope-like compositions comprising 1,2,3,3,3-pentafluoropropene (HFO-1225ye), water and at least one impurity, wherein the impurity is halocarbon or hydrogen fluoride. Also provided are methods of purifying such azeotropic and azeotrope-like compositions in order to recover purified 1,2,3,3,3-pentafluoropropene.
