Abstract

Procédé de préparation du citronellal et de ses homologues par hydrogénation sélective du citral et de ses homologues en présence d'un catalyseur à base de palladium et d'une base, caractérisé en ce que la réaction est conduite en absence d'eau et en présence d'au moins 10 % en poids par rapport au citral ou à ses homologues, d'une base hétérocyclique prise dans le groupe formé par la pyridine, la quinoléïne, l'hydroxy-8 quinoléïne.
