【Abstract】 Titanium tartrate complex has been embedded into the super-cage of NaY zeolite carriers by using a "ship-in-bottle" method, which was confirmed by FT-IR. and UV-Vis diffuse reflection spectra . In catalyzing the epoxidation of cinnamyl alcohol with TBHP as an oxidant, Ti complex encapsulated into NaY showed the high catalytic turnover numner and the better selectivity for the epoxides than Ti complex grafted onto HMS. The reused test indicated that NaY-Ti-DET possessed the excellent stability, and could be recovered and repeatedly used many times without being loss of activity.更多还原
