ВЛИЯНИЕ РЕЖИМОВ ТЕРМИЧЕСКОГО ВОССТАНОВЛЕНИЯ НА ФОРМИРОВАНИЕ, УСТОЙЧИВОСТЬ И КАТАЛИТИЧЕСКИЕ СВОЙСТВА ПОЛИМЕРСТАБИЛИЗИРОВАННЫХ НАНОЧАСТИЦ ПАЛЛАДИЯ В РЕАКЦИИ СЕЛЕКТИВНОГО ГИДРИРОВАНИЯ АЦЕТИЛЕНОВЫХ СПИРТОВ

Thermal destruction of palladium acetate at temperatures ranging from 200 to 325 °C in an industrial hypercrosslinked polystyrene MN-270 was investigated by TGA and XPS and described in this article. The studies have shown that the palladium acetate distributed into hypercrosslinked polystyrene collapses with forming of metal palladium at lower temperatures than the pure salt powder. The formation and stabilization of palladium clusters Pd7–Pd10 and their partial aggregation with the formation of palladium nanoparticles happens during the of destruction. The catalytic testing of obtained systems in the selective hydrogenation of the triple bond dimethyl-ethynyl carbinol in toluene at 90 °C showed their considerable superiority in activity and selectivity in comparison with a commercial Lindlyar catalyst: TOF increase more than doubled when the selectivity 97,8 %.
