In the article, in order to evaluate the effect of various factors on the oxidation process of n-butane, a series of experiments were conducted at a temperature of 170 ℃ for 58 hours with the mixing of reactants in a reactor at a speed of 0.05 m amplitude 2s-1. Infrared spectroscopy, transmission electron microscopy, and powder X-ray diffraction data were reported. According to infrared spectroscopy, when the ratio of tetra-Npropylammonium hydroxide/tetraethoxysilane is less than 0.085, it is proved that the main product is a mixture of amorphous titanium(IV) oxide and the amorphous form of titanium(IV) oxide is amorphous silicon(IV) oxide. Powder X-ray diffraction of the samples also showed the X-ray appearance of amorphous titanium(IV) oxide peaks. According to electron microscopy, a change in the size of the catalyst particles is observed as the initial molar ratio of tetra-N-propylammonium hydroxide/tetraethylorthosilicate increases. As a result of the study of the effect of temperature on the reaction rate, it was proved that the productivity of butanone-2 increased from 13.65% to 30.85% and the conversion rate of potassium permanganate solution increased from 37.5 to 97.2% with an increase in temperature from 50 ℃ to 90 ℃. It should be noted that the initial tetra butyl titanatetetraethylorthosilicate molar ratio is xTiO2•(1-x)SiO2 (x=0.0001-0.04) with 33% porosity obtained by reaction in aqueous solutions at temperatures above 100 ℃ and pressures above 1 atmosphere. ) has a significant effect on the obtained samples of the catalyst.
