Abstract

The liquid-phase hydrogenation of benzylideneaniline over various Pd catalysts, using gaseous hydrogen has been studied. We have synthesized several Pd catalysts (3 wt.%) over SiO2−AlPO4 and sepiolite supports, and determined their metal surface area by X-ray diffraction. The study performed shows that the process follows a Langmuir-Hinshelwood kinetics with zero order in benzylideneaniline, ri=kokPH2 (1+KPH2)−1.

Abstract

Исследовали Зидкофазнуй гидрогенизацию бенилиденанилина на различных катализаторах Pd, используя газовый водород. Синтезировали несклько Pd катализаторов (3 вес.%) на носителях SiO2−AlPO4 и сепиолите. Рентгено-диффракционным методом определяли площадь поверхности металла. Показано, что процесс подчиняется кинетике Лангмюра-Хиншельвуда с нулевым порядком по бензилиденанилину, ri=kokPH2 (1+KPH2)−1.
