  • Methods for preparing epoxides
    Publication number: 20080114193
    Abstract: The invention includes methods for preparing halohydrins and epoxides. A method of preparing halohydrins can include exposing (R1CHXCH2O—)2SO2 to R2COOH to produce R2COOCH2CHXR1 and hydrolyzing the R2COOCH2CHXR1 to produce the halohydrin R1CHXCH2OH. R1 and R2 can be the same or different single elements and/or organic groups and X can be a halogen. A method of preparing an epoxide can include combining a sulfuric acid containing solution with a halogen to produce a first mixture and exposing the first mixture to trifluoropropene to produce a second mixture. The second mixture can be combined with acetic acid to produce an acetyl halohydrin of trifluoropropene and the acetyl halohydrin can be hydrolyzed to form a halohydrin of trifluoropropene. The halohydrin can be converted to a trifluoropropyl epoxide.
