Process for producing olefin oxides by means of the reaction of an olefin with oxygen or air, in the presence of a catalyst constituted by titanium silicalite and a redox system comprising alkyl-anthrahydroquinone and alkyl-anthraquinone, with said reaction being carried out in a solvent mixture consisting of: (a) one or more aromatic or alkyl-aromatic, mono- or polynuclear hydrocarbon(s) selected from among benzene, toluene, xylene, alpha-methyl-naphthalene or halogenated derivatives thereof, such as dichlorobenzene; (b) one or more polar organic compound(s) with boiling point comprised within the range of from 150 to 350 DEG C, and selected from among di-isobutyl-carbinol, di-isobutyl-ketone, methyl-cyclohexyl acetate, dimethyl phthalate, dibutyl phthalate, diethylhexyl phthalate and tributyl phthalate; (c) a low molecular weight alcohol, preferably methanol. <IMAGE> |
