- Abstract
The catalytic properties of mesoporous amorphous titanosilicate Ti–Si in acetone homocondensation at 250–350°С and mass feed space velocity of 0.5–10 h–1 were studied. The acetone conversion was 13–52 wt %, and the selectivity with respect to mesitylene was 52–70 wt %. A kinetic model based on the experimentally developed scheme of chemical transformations was constructed; it includes 10 steps and takes into account the effect of water. The retrieval of the kinetic parameters was implemented in the form of a global optimization problem, which allowed determination of the kinetic constants, adsorption constant, activation energy, and heat of adsorption of water.
