ABSTRACT:
Zeolites containing silicon, titanium and tellurium oxides are prepared by a hydrothermal method which yields materials containing exceptionally high levels of catalytically active Ti species. Following calcination, the molecular sieves are active and selective catalysts for the epoxidation of olefins using hydrogen peroxide or organic hydroperoxide. The zeolites may have framework structures of varying topology, including MFI, MEL, BEA, ZSM-48, MTW or MCM-41.
