Název v původním jazyce

Competitive hydrogenation in binary diene systems on a palladium catalyst

Popis výsledku v původním jazyce

Hydrogenations of individual C5 dienic substrates (1,3-cyclopentadiene, isoprene, 1,4-pentadiene, cis-1,3-pentadiene, trans-1,3-pentadiene) and their binary mixtures on a heterogeneous palladium catalyst were studied in cyclohexane at 25°C and 2 MPa. Selectivities of the competitive hydrogenations were determined and the substrates relative adsorption coefficients calculated. Effects of the diene structure on their reactivity and the stability of the surface complex were discussed. It was found, that differences in selectivity of the competitive hydrogenations of C5 dienes are caused by both the difference in adsorptivity values and the difference in reactivity of adsorbed molecules. The presence of five-member ring in the molecule of C5 dienes results, compared to acyclic structures of C5 dienes, in significant reduction of surface complex stability. On the other hand, it has very positive effect on the rate of surface reaction.
