Abstract
Processes for the preparation of certain halogenated aliphatic ethers are described, and in particular the preparation of 1,1,2-trifluoro-2-chloroethyl methyl ether, i.e., CH.sub.3 OCF.sub.2 CHFCl. This particular ether has many uses, and is a valuable material for use in the production of the inhalant anesthetic enflurane, 1,1,2-trifluoro-2-chloroethyl difluoromethyl ether, i.e., CF.sub.2 HOCF.sub.2 CHFCl, made and sold under the trademark ETHRANE by Airco, Inc., Montvale, New Jersey 07645.
