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