ABSTRACT:
A novel process is disclosed for the synthesis of fluorinated dimethyl ethers of the formula CF.sub.2 HOCCl.sub.X F.sub.Y H.sub.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.sub.2 HOCH.sub.3-z Cl.sub.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.
