Abstract

Gas phase hydrogenation of m-xylene on palladium supported catalysts was studied and compared with the hydrogenation of o-xylene. The modification in the stereoselectivity of palladium due to an increase in the acidity of the support is explained in terms of an increased residence time of the reactive species on the active surface, leading to a product composition closer to that predicted by thermodynamics.

Abstract

Газофазное гидрирование м-ксилола на нанесенных палладиевых катализаторах исследовали и сравнивали с гидрированием о-ксилола. Изменения в стереоселективности палладия за счет повышения кислотности носителя объясняют повышенными временами местопребывания реактивных частиц на активной поверхности, приводя к продукту со строением, более близким к предсказанному термодинамикой.
