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 is 0, 1 or 2; y is 1, 2 or 3; and wherein the total x+y is 1, 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 HF and/or an antimony salt and with or without separation from the chlorinated reaction product, to give a fluorinated reaction product including the aforementioned fluorinated dimethyl ethers. |
