1424284 Epoxidizing olefins SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 9 March 1973 [13 March 1972] 11456/73 Addition to 1339309 Heading C2C [Also in Division B1] Oxiranes are produced by the reaction of one or more olefinic compounds with one or more hydroperoxides in the presence of solid catalyst comprising an inorganic oxygen compound of silicon and an oxide or hydroxide of Ti, Mo, V, Zr or B which has been contacted with an organodisilazane at elevated temperature. The olefinic compound suitably contains 2 to 60 carbon atoms and may be a C 3 to C 40 alkene which may be substituted with a hydroxyl group or halogen atom, e.g. propylene, allyl alcohol or allyl chloride. The hydroperoxide may contain 3 to 20 carbon atoms, e.g. tertbutyl- or tert-pentyl-hydroperoxide or aralkylhydroperoxides in which the hydroperoxy group is linked to that carbon atom of an alkyl side chain which is attached directly to an aromatic ring such as 1-phenylethyl-1-hydroperoxide (ethyl benzene hydroperoxide) and 2-phenylpropyl - 2 - hydroperoxide (cumene hydroperoxide). The reaction may be carried out at 0-200‹ C. The example describes the reaction of octene-1 and ethyl benzene hydroperoxide. |
