1.The rate constants of hydrogenation k0, the adsorption coefficients b, and the relative reactivity S in the competitive hydrogenation of methyl esters of aromatic acids on a Ru/C catalyst were determined.2.The decrease in the rate of hydrogenation of the aromatic ring of the ester and the value of its relative adsorption coefficients when a new substituent is introduced is due to a substantial degree to steric hindrance.3.The disruption of the correlation of k0 and b from methyl benzoate to methyl p-aminobenzoate is explained by displacement of H2 as a result of the strong adsorption of the amino derivative and its hydrogenation product. |
