Preparation of Mesoporous Organically Modified Titanium Materials and their Activity in the Oxidation of Cyclohexene
Mesoporous organically modified Ti-MCM-41 materials were synthesised employing different Ti precursors. Materials were found to possess improved properties in terms of stability, hydrophobicity and activity compared to the parent Ti-MCM-41, preserving their mesoporous structural order. The organically modified mesoporous materials were tested in the oxidation of cyclohexene using conventional heating and microwaves. The microwave assisted protocol was found to enhance reaction rates and selectivities to the epoxide, reducing the times of reaction from 24 to less than 1 h at comparable activities (60-80% conversion).
