Abstract
A heterogeneous catalyst suitable for use in an olefin epoxidation reaction is obtained using a titanosiloxane polymer as a source of titanium. The titanosiloxane is combined with an inorganic siliceous solid such as silica or a siliceous sol gel to form a catalyst precursor composition. Calcination yields the active titanium-containing catalyst.
