A subject of the present invention is a process for the reduction of a carbonyl compound. More precisely, the invention relates to a process for reduction of an aldehyde and/or of a ketone. The reduction process of the invention, which consists of reacting a carbonyl compound with an alcohol in the presence of a zeolite catalyst, is characterized by the fact that it comprises: mixing, in any manner whatever, the carbonyl compound and the alcohol, passing said mixture over a catalyst bed containing at least one zeolite, subjecting the reaction mixture leaving the catalyst bed to recirculation over the catalyst bed, for a number of times that is sufficient to obtain the desired degree of conversion of the substrate.
