Реферат: The synthesis of HA modified by Mg2+ and SiO4 4- ions was performed to determine the modifying effect of ions on the acid and catalytic properties for oxidative dehydrogenation of propane. The acidity of the surface was determined by low temperature FTIR spectroscopy of adsorbed CO. It was found that the introduction of Mg2+ and SiO4 4- ions into the structure of HA did not alter the hydroxyapatite structure, but it led to increased surface acid properties. The sample modified by magnesium showed the highest activity and selectivity in the oxidative dehydrogenation of propane. The achieved total selectivity in the formation of ethylene and propylene at 550oC over this catalyst was 57% at conversion of 17%.
