An improved process for the production of isoflurane is disclosed. Isoflurane is formed by the exhaustive chlorination of 2,2,2-trifluoro- ethyl difluoromethyl ether with chlorine gas. The reaction mixture, preferably without purification or refining, is treated with UV light in the presence of isopropanol to reduce 1,1-dichloro-2,2,2-trifluoroethyl difluoromethyl ether, the other major component thereof, to isoflurane. Isoflurane is thereby obtained in yields of at least 80%. |
