Abstract
The oxidation of olefinic compounds generally using hydroperoxides, especially aqueous solutions of hydrogen peroxide, can be effected in high yield and with good selectivity in the presence of a titania-supported titanosilicate catalyst. Dilute aqueous hydrogen peroxide solutions may be used with good results. The resulting epoxidation, even when carried out at modest temperatures and with dilute aqueous hydrogen peroxide solutions, afford superior results in epoxidation relative to TS-1.
