Abstract
Alkene oxides are produced by the reaction of an organic hydroperoxide and an alkene in the presence of a catalyst of an inorganic oxygen compound of silicon in chemical combination with an oxide or hydroxide of titanium.
Claims19
A process of epoxidizing propylene by reacting, in liquid phase in inert solvent at a temperature of about 25.degree. C. to 200.degree. C., propylene with a hydrocarbon hydroperoxide selected from tertiary alkyl hydroperoxide of from 4 to 20 carbon atoms and aralkyl hydroperoxide of from 7 to 20 carbon atoms wherein the hydroperoxy group is on a carbon atom attached directly to an aromatic ring in the presence of a heterogeneous essentially insoluble catalyst composition comprising an inorganic oxygen compound of silicon in chemical combination with at least 0.1% by weight, based on total catalyst composition, of an oxide or hydroxide of titanium.
A process of epoxidizing a linear terminal alkene of 3 to 40 carbon atoms by reacting, in liquid phase an inert solvent at a temperature of about 25.degree. C. to 200.degree. C., the alkene with a hydrocarbon hydroperoxide selected from tertiary alkyl hydroperoxide of from 4 to 20 carbon atoms and aralkyl hydroperoxide of from 7 to 20 carbon atoms wherein the hydroperoxy group is on a carbon atom attached directly to an aromatic ring in the presence of a heterogeneous, essentially insoluble catalyst composition comprising an inorganic oxygen compound of silicon in chemical combination with at least 0.1% by weight, based on total catalyst composition, of an oxide or hydroxide of titanium.
