Abstract Methyl linoleate was hydrogenated in the vapor phase in the presence of a nickel on alpha‐alumina catalyst. A reaction mechanism was proposed to explain the fact that the selectivity is influenced by the hydrogen pressure. A rate equation was derived based on the mechanism and the rate constant was evaluated from kinetic experiments. The adsorption coefficients in the rate equation were based on separately performed adsorption studies recently published.
