Disclosed is a method for selective hydrogenation of citronellal to form citronellol, wherein a liquid phase in which the citronellal is dissolved and in which particles of a catalyst are suspended, said catatalyst resulting in preferential hydrogenation of carbon-oxygen double bonds in relation to carbon carbon bonds, is guided in the presence of a gas containing hydrogen through a device which inhibits the transport of the catalyst particles.
La présente invention concerne un procédé d'hydrogénation sélective de citronellal en citronellol. Ce procédé consiste à faire passer une phase liquide dans laquelle est dissous le citronellal et dans laquelle sont en suspension des particules d'un catalyseur qui présente un pouvoir d'hydrogénation préférentiel de doubles liaisons carbone-oxygène par rapport aux doubles liaisons carbone-carbone, en présence d'un gaz contenant de l'hydrogène, à travers un dispositif qui empêche le transport des particules de catalyseur.
