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 catalyst which is a mixture of small particles of titania and a titanosilicalite. Small particle size is essential in affording a catalyst with good activity and selectivity, with particle sizes no more than about 0.3 microns being the preferred mode of operation. 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.
