Summary 1. A procedure for the study of liquid-phase catalytic hydrogenation is described. Suitable apparatus has been devised, and a method is proposed for the determination of surface concentrations in the hydrogenation process. 2. It was shown that, in 96% alcohol over Raney nickel, maleic acid is adsorbed and hydrogenated more readily than fumaric acid. Succinic acid has a displacing action on maleic and fumaric acids. In a mixture of acids in 96% alcohol over Raney nickel, fumaric acid is adsorbed more readily than maleic acid, but is hydrogenated more slowly. 3. In the study of catalytic-hydrogenation processes in a mixture, it is necessary to take into account the surface concentrations of the reactants at the moment of reaction.
