Abstract
Ti-Co-MCM-41 molecular sieve catalysts were synthesized using the impregnation method. The catalysts were characterized by X-ray diffraction, UV-visible, Fourier transform infrared spectroscopy and low temperature N2 adsorption-desorption. Their performance in 4-tert-butylbenzaldehyde synthesis was evaluated in mild conditions by oxygen oxidation 4-tert-butyltoluene. The results showed that the catalysts had large surface area and pore size and contained titanium and cobalt with four ligands, which formed the catalysts of high catalytic activity. The conversion rate of 4-tert-butyl toluene was improved by 38 %, the selectivity of 4-tert-butyl benzaldehyde was improved by 85 % and the yield of 4-tert-butyl benzaldehyde was up to 35 %.
