Epoxidation of 2-buten-1-ol over Ti-MCM-41 and Ti-MCM-48 titanium silicalite catalysts

Real-Time Raman Monitoring during Photocatalytic Epoxidation of Cyclohexene over V-Ti/MCM-41 Catalysts

A series of Vand/or Ti-loading MCM-41 catalysts are successfully synthesized with a hydrothermal method. The photocatalytic and thermal epoxidations of cyclohexene in the presence of tert-butyl hydroperoxide (t-BuOOH) were investigated with real-time monitored by NIR-Raman spectroscopy. It suggests that both Vand Ti-loading can be responsible for the cyclohexene epoxidation. Moreover, the compl...

Artificial sunlight and ultraviolet light induced photo-epoxidation of propylene over V-Ti/MCM-41 photocatalyst

The light irradiation parameters, including the wavelength spectrum and intensity of light source, can significantly influence a photocatalytic reaction. This study examines the propylene photo-epoxidation over V-Ti/MCM-41 photocatalyst by using artificial sunlight (Xe lamp with/without an Air Mass 1.5 Global Filter at 1.6/18.5 mW·cm(-2)) and ultraviolet light (Mercury Arc lamp with different f...

Photodecomposition of Water Catalyzed by Zr- and Ti-MCM-41

Ti-MCM-41 materials synthesised at room temperature as catalysts for cyclisation of (±)-citronellal

Citronellal can be cyclised to produce isopulegol, which is an intermediate in the synthesis of menthols. These chemicals are all used in the fragrance industry and menthol is also an important product used as a flavour, a pharmaceutical and in oral care. The cyclisation of citronellal proceeds readily with various homogeneous catalysts, but the catalyst frequently cannot be recovered and reuse...
