Reaction Pathway and Selective Hydrogenation on Catalyst Derived from Oxidation Treatment of Mg2Cu Alloy

Article abstract of DOI:10.1246/bcsj.67.1548

A catalyst derived from oxidation treatment of Mg2Cu alloy was studied in a gas-phase continuous-flow reactor under atmospheric pressure to investigate the specific selectivity for hydrogenation.In order to propose the reaction pathways for hydrogenation of long chain unsaturated ester, reactivities of characteristic functional groups were tested.The reactions of ester and aldehyde groups showed higher selectivity to alcohols than to paraffins.We concluded from competitive reactions of two reactants that hydrogenation of unsaturated bond group was inhibited by the adsorption of ester or aldehyde group.The effect of partial pressure on each reaction rate was summarized into the Langmuir equation.The main route to unsaturated alcohol and reasons for the increased selectivity to alcohol are discussed.
