Catalytic activity of Ti(IV) salen as active catalyst in the epoxidation of olefin

초록

A route to synthesize silicalite crystals with a bimodal micro/mesoscopic pore system has been developed in this study: The successful incorporation of the mesopores within the silicalite structure was perform by post-synthetic method using alkaline (NaOH) solution. Titanium salen complex was successfully immobilized into the pore system of mesoporous Silicalite, and epoxidation of (-)-α-pinene using H2O2 was employed as a test reation. Mesoporous catalyst has shown the excellent activity ( epoxide yield to 81%) and high stability (with the 4th repeated use) in that reaction.
