Disclosed is a process for the preparation of a dimethyl cyclohexanedicarboxylate by the hydrogenation of the corresponding dimethyl benzenedicarboxylate ester in the presence of a class of supported catalysts comprising palladium and a second Group VIII metal selected from nickel, platinum, ruthenium or a mixture thereof deposited on an alumina support which have a unique combination of characteristics. The use of the catalysts permits the process to be carried out at significantly lower process pressures.

On divulgue le mode de préparation d'un cyclohexanedicarboxylate de diméthyle par hydrogénation de l'ester correspondant, le benzènedicarboxylate de diméthyle, en présence de catalyseurs sur support, constitués de palladium et d'un deuxième métal du groupe VIII choisi parmi le nickel, le platine ou le ruthénium, ou d'un mélange de ces métaux, déposés sur un support d'alumine possédant une combinaison unique de caractéristiques. L'emploi de ces catalyseurs permet d'effectuer la préparation à des pressions beaucoup plus faibles.
