Substituent effects in heterogeneous catalysis--4. Adsorption estimations during competitive hydrogenation of cyclohexanone and its 2-alkyl derivatives

Abstract

Adsorption estimations during competitive hydrogenation of cyclohexanone and its 2-alkyl derivatives alumina-supported ruthenium, rhodium, and platinum catalysts were obtained in a study to determine the relative contributions of the rate constants and the adsorption equilibrium constants to the substituent-dependent constant. The reaction rates obtained during competitive hydrogenation were in the order cyclohexanone (A) Vertical Bar3:Vertical Bar3: 2-methyl cyclohexanone (B) Vertical Bar3: 2-ethyl cyclohexanone (C) Vertical Bar3: 2-propyl cyclohexanone (D) for all catalysts, whereas the rates obtained during individual hydrogenation were in the order A Vertical Bar3: B approx. C approx. D. The adsorption equilibrium constants which were estimated by analyzing the kinetic data agreed well with the theoretical values derived from statistical mechanics by using a model in which the substrate ketones were immobilely adsorbed.
