A process for synthesizing difluoromethyl methyl ether for use for example as refrigerants and blowing agents is disclosed. This process involves (1) feeding chlorodifluoromethane through a solution of sodium methoxide in methanol or basic ion exchange resin in methanol at a rate from about 0.5 to 5 grams of feed gas per gram of solution per minute; (2) removing the gaseous product and the unreacted chlorodifluoromethane continuously; and (3) separating difluoromethyl ether from the unreacted chlorodifluoromethane.
