    • 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.
    • 本发明的主题是还原羰基化合物的方法。 更准确地说,本发明涉及还原醛和/或酮的方法。 在沸石催化剂存在下使羰基化合物与醇反应的本发明的还原方法的特征在于:其包括:以任何方式混合羰基化合物和醇,通过所述 混合物在含有至少一种沸石的催化剂床上,使离开催化剂床的反应混合物在催化剂床上再循环足够多的时间以获得所需的底物转化率。
