摘要： Provided are azeotropic and azeotrope-like compositions of 1,2,3,3,3-pentafluoropropene (HFO-1225ye) and water. Such azeotropic and azeotrope-like compositions are useful in isolating 1,2,3,3,3-pentafluoropropene from impurities during production. Azeotropes of the instant invention are similarly useful in final compositions or manufacturing final compositions, such as blowing agent, propellants, refrigerants, diluents for gaseous sterilization and the like.

摘要： The present invention is a method for purifying a linear saturated fluorohydrocarbon compound comprising bringing a crude linear saturated fluorohydrocarbon compound having four or five carbon atoms into contact with a hydrous metal salt of a synthetic crystalline aluminosilicate that has a carbon dioxide adsorption amount of 50 μmol/g or less and an average pore size of 3 Å to remove water from the crude linear saturated fluorohydrocarbon compound. The present invention makes it possible to reduce or suppress the production of a dehydrofluorinated compound due to a decomposition reaction of the linear saturated fluorohydrocarbon compound, and to remove water efficiently.
