“…. Previous catalytic studies have shown that the modification of aluminum oxide affects its properties during the conversion of isopropyl alcohol [9][10][11]. Taking this into account, the aim of the study was the study of thermal resistance before and after the impregnation of phosphormolybdenum heteropoly acids on ηaluminum oxide, as well as after participating in the catalytic process.…”

The methods of thermal analysis – thermogravimetry, differential thermal analysis – were used to study the catalytic system phosphor-molybdenum heteropoly acid–aluminum oxide. It is shown that the modification of aluminum oxide has a direct effect on the state of the phosphor-molybdenum heteropoly acid. On the surface of ƞ-Al2O3, phosphomolybdic acid is destroyed by interaction with strong Lewis’s acid sites of the carrier, while on γ-Al2O3 it retains the individuality, probably due to multipoint adsorption on weak Bronsted and Lewis acid sites of the oxide
