ABSTRACT OF THE DISCLOSURE A novel process is disclosed for the synthesis of fluorinated dimethyl ethers of the formula CF,HOCC1xFyH3-(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,HOCH3-2C1, 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.
