Abstract

Hydrogenation of 2-phenyl-1-propene and 1-hexene in ethanol, toluene and benzene was studied on platinum black modified by ad-atoms of lead, thallium, and bismuth. The experimental dependences of the specific hydrogenation rate on the degree of coverage by the metal ad-atoms are interpreted under the assumption that the substrate and hydrogen take part in the reaction and at low degree of the coverage, the organic substance is adsorbed on the modified and non-modified surfaces to the same extent.
