Esterification and polymerization by catalytic oxidation of cyclohexane at room temperature over modified sulfated TiO2 in the air

The products of esters and long-chain alkanes were obtained by one step of the catalytic oxidation of cyclohexane at room temperature over modified sulfated TiO2 in the air. It is a clean and convenient way to achieve esterification and polymerization. Such products are very important to improve the quality of the fuel. Several catalysts related to TiO2 were prepared and characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy techniques. From the molecule structure and its atomic valence of the SO42-/TiO2-Co2O3, it can be confirmed that the modified sulfated TiO2 efficiently reacted with the reaction. According to the results of UV and gas chromatography-mass spectrometry, SO42-/TiO2-Co2O3 exhibited better catalytic activity than the other catalysts. The value and yield of the products were also discussed.
