Abstract

Fluorinated dimethyl others of the formula CF2HOCClxFyH3-(x+y) wherein x is 0, 1, or 2, y is 1, 2, or 3 and the total x + y is 1, 2 or 3, are prepared by chlorination of methyl difluoromethyl ether to form a chlorinated reaction product, including at least one compound of the formula CF2HOCH3-zClz 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 others.
