A 1 liter stainless steel autoclave (Parr) was charged with 127.3 g (2.19 mole) of potassium fluoride and 434.6 g (2.01 mole) of (CF3)2CHOCH2Cl. The autoclave was then sealed and the reaction mass heated at 185° C. for 19 hours, during which time a pressure of 280 psi developed. The reactor was then cooled, the contents treated with water and the organic material distilled to afford 241 g (1.21 mole) of (CF3)2CHOCH2F and 80 g (0.4 mole) of (CF3)2CHOCH2Cl, corresponding to a 60% conversion (75% yield). The structure of (CF3)2CHOCH2F (Sevoflurane), b.p. 56° C., may be confirmed by the following instrumental data:

1. customThe autoclave was then sealed
