Patent number: 8692038Abstract: There is provided a fluorine-containing compound purification method for obtaining a high-purity fluorine-containing compound by efficiently separating and removing hydrogen chloride from a fluorine-containing compound that contains hydrogen chloride, i.e., from a crude fluorine-containing compound. The fluorine-containing compound purification method of the present invention comprises the following steps (1) and (2) in this order: step (1): a step of adding dimethyl ether to a crude fluorine-containing compound that contains a fluorine-containing compound and hydrogen chloride in a molar ratio (dimethyl ether (mol)/hydrogen chloride (mol)) of dimethyl ether to hydrogen chloride being 1.3 or more to prepare a mixture (1) of the crude fluorine-containing compound and dimethyl ether; and step (2): a step of separating and removing a mixture (2) of hydrogen chloride and dimethyl ether from the mixture (1).Type: GrantFiled: October 26, 2010Date of Patent: April 8, 2014Assignee: Showa Denko K.K.Inventors: Hiromoto Ohno, Toshio Ohi, Katsutoshi Morinaka
