METHOD FOR PURIFYING FLUOROOLEFIN, AND METHOD FOR PRODUCING FLUOROOLEFIN

摘要

PROBLEM TO BE SOLVED: To provide a method for purifying a fluoroolefin by adsorbing off a 1 or 2C impurity from a fluid mixture containing a ≥3C fluoroolefin.SOLUTION: A method for purifying a fluoroolefin is characterized by contacting a ≥3C fluoroolefin and a 1 or 2C hydrocarbon whose at least one hydrogen atom may be replaced by chlorine atom or fluorine atom with synthetic zeolite 5A to remove the 1 or 2C hydrocarbon.
