KINETICS OF NITRILE HYDROGENATION. The effect of Palladium Particle Size in Pd/Al2O3 Catalysts
Original language description
Heterogeneously catalyzed nitrile hydrogenation is one of the basic methods of industrial production of many important amines. Generally, this reaction leads to a mixture of primary, secondary and tertiary amines. The chemical nature of metal in the catalyst has decisive influence on the reaction selectivity; the effects of other reaction parameters are much less pronounced. In this study, the effect of palladium particle size in Pd/Al2O3 catalysts on the kinetics of hydrogenation of model nitrile, isobutyronitrile, has been studied. The mixture of diisobutylamine and triisobutylamine was the product of the liquid-phase hydrogenation catalyzed by series of 2.9% Pd/Al2O3 catalysts varied in their size of elementary Pd crystallites with the range of 2.2 to 32 nm. The specific activity of the catalyst in the hydrogenation was found to decrease with increasing value of particle size. Further, an increase of Pd particle size resulted in a slightly increased formation of the secondary amine at the expense of the tertiary one.
