A novel process is disclosed for the synthesis of fluorinated dimethyl ethers of the formula CF 2 HOCCl X F Y H 3- (X+Y) wherein X and Y are each independently 0, 1, 2 or 3 and wherein the total X+Y is 2 or 3. The process involves chlorination of methyl difluoromethyl ether to form a chlorinated reaction product, including at least one compound of the formula CF 2 HOCH 3-z Cl z , wherein z is 1, 2 or 3, which compound is then fluorinated, with or without separation from the chlorinated reaction product, to give a fluorinated reaction product including the aforementioned fluorinated dimethyl ethers. |
