Effect of the Structure of Unsaturated Hydrocarbons and Alcohols on Their Reactivity and Adsorptivity in Hydrogenation

Competitive hydrogenations of unsaturated hydrocarbons and unsaturated alcohols using a palladium supported catalyst, were studied under atmospheric pressure at 25 °C. From the acquired data and from the hydrogenation of each individual substrate, kinetic and adsorption parameters were determined. It was found that the hydroxyl group position relative to the double bond has no significant effect on the reactivity of the studied unsaturated alcohols; however, it has a major effect on their adsorptivity. Reactivity and adsorptivity of unsaturated hydrocarbons depended on the double bond position in substrates.
