ABSTRAKT

We focus on the preparation and use of mesoporous TiSBA-15 (Santa Barbara Amorphous) material with different Si/Ti mass ratios. Catalysts with different Si/Ti mass ratios were prepared and characterized by several techniques including X-ray powder diffraction, Fourier-transform infrared (FTIR) spectroscopy, and Brunauer–Emmett–Teller surface area analysis. N2 adsorption and desorption isotherms revealed that all of the catalysts have large surface areas (∼ 900 m2/g) and pore diameters in the range of mesopores (∼ 7 nm), making them suitable catalysts for bulky molecular transformation reactions. Catalyst activity was examined for the preparation of a biolubricant from the epoxidation of canola oil. Canola oil epoxidation was carried out at 70°C, with a canola oil–to–hydrogen peroxide molar ratio of 1:14 and catalyst loading of 5 wt%. TiSBA-15 with a mass ratio of 20 resulted in 88% conversion based on unsaturation. The oxirane oxygen content of the product was 1.66, and the formation of an epoxide product of canola oil was confirmed by FTIR, 1H nuclear magnetic resonance (NMR), and 13C NMR spectral analysis. These studies showed that TiSBA-15 with the mass ratio of 20 shows promise for the preparation of epoxidized canola oil that can act as a starting material for lubricant formulation. On the basis of these results, we conclude that this system could have great potential for industrial use.
