摘要： Provided is a process for purifying a fluorine compound capable of yielding a highly pure fluorine compound by removing at least oxygen from a fluorine compound containing an oxygen compound as an impurity. In a process according to the present invention for purifying a fluorine compound, the following is brought into contact with the fluorine compound, which contains an oxygen compound as an impurity, thereby removing at least oxygen: carbonyl fluoride in an amount of a 0.1-fold equivalent or more and a 100-fold equivalent or less of oxygen atoms in the fluorine compound.
