Abstract
Pt/sol and Pt/support catalysts with 6–15 Å Pt particles have been established to be low active in the hydrogenation of propargyl alcohol, butyn-l-ol-3 and dimethylethynylcarbinol. The specific catalytic activity significantly rises with increasing dPt above 15 Å and after the thermal treatment of highly dispersed catalysts in a hydrogen flow.
Abstract
Показано, что Рт-30ли и Рт-носитель-катализаторы с размером частиц платины 6–15 Å малоактивны в реакции гидрогенизации пропаргилового спирта, бутин-1, ола-3 и диметилэтинилкарбинола. Значительный рост каталитической активности происходит при увеличении dPt>15 Å и термической обработке высокодисперсных катализаторов в токе водорода.
