Title (EN) PROCESS FOR THE HYDROGENATION OF GLYCOLALDEHYDE
(FR) PROCÉDÉ D'HYDROGÉNATION DE GLYCOLALDÉHYDE
Abstract:
(EN) The invention provides a process for the selective hydrogenation of glycolaldehyde in a process stream comprising glycolaldehyde and one or more monosaccharide in a solvent, said process comprising contacting the process stream with hydrogen in the presence of a hydrogenation catalyst composition at a temperature of no more than 150°C and for a residence time of no more than 90 minutes.
(FR) L'invention concerne un procédé d'hydrogénation sélective de glycolaldéhyde dans un flux de traitement comprenant du glycolaldéhyde et au moins un monosaccharide dans un solvant, ledit procédé comprenant la mise en contact du flux de traitement avec de l'hydrogène en présence d'une composition catalytique pour l'hydrogénation, à une température de 150°C au maximum et pendant un temps de séjour inférieur ou égal à 90 minutes.
