Title
(EN) PROCESS FOR THE PREPARATION OF 1,2-PROPANEDIOL FROM GLYCEROL
(FR) PROCÉDÉ POUR LA PRÉPARATION DE 1,2-PROPANEDIOL À PARTIR DE GLYCÉROL
Abstract
(EN)
The present invention relates to a process for the preparation of 1,2-propandiol, at least comprising the following steps a) providing a glycerol-containing stream comprising at least 40% by weight of at least one organic solvent and b) subjecting the glycerol-containing stream of step a) to a hydrogenation in the presence of a copper-containing, heterogeneous catalyst at a pressure of at least 50 bar.
(FR)
La présente invention porte sur un procédé pour la préparation de 1,2-propanodiol, comprenant au moins les étapes suivantes consistant à a) se procurer un courant contenant du glycérol comprenant au moins 40 % en poids d'au moins un solvant organique et b) soumettre le courant contenant du glycérol de l'étape a) à une hydrogénation en présence d'un catalyseur hétérogène contenant du cuivre à une pression d'au moins 50 bar.
