Title (EN) A METHOD OF PREPARING GLYCOLIC ACID (HOCH2COOH)
(FR) PROCÉDÉ DE PRÉPARATION D’ACIDE GLYCOLIQUE (HOCH2COOH)
Abstract:
(EN) The present invention provides a method of preparing glycolic acid ( HOCH2COOH ), the method at least comprising the steps of: (a) providing an aqueous oxalic acid (HOOCCOOH) containing stream having a molar ratio of water/oxalic acid of above 5.0; (b) subjecting the aqueous oxalic acid (HOOCCOOH) containing stream provided in step (a) to hydrogenation in the presence of a hydrogenation metal catalyst and hydrogen, thereby obtaining a glycolic acid (HOCH2COOH ) containing stream; and (c) optionally subjecting the glycolic acid containing stream obtained in step (b) to hydrogenation in the presence of a hydrogenation metal catalyst and hydrogen, thereby obtaining an ethylene glycol ( HOCH2CH2OH ) containing stream.
(FR) La présente invention concerne un procédé de préparation d’acide glycolique (HOCH2COOH), le procédé comprenant au moins les étapes de : (a) fourniture d’un flux contenant de l’acide oxalique (HOOCCOOH) aqueux ayant un rapport molaire d’eau/acide oxalique supérieur à 5,0 ; (b) soumission du flux contenant de l’acide oxalique (HOOCCOOH) aqueux produit dans l’étape (a) à une hydrogénation en présence d’un catalyseur métallique hydrogénation et d’hydrogène, de manière à obtenir un flux contenant de l’acide glycolique (HOCH2COOH) ; et (c) facultativement, soumission du flux contenant de l’acide glycolique obtenu dans l’étape (b) à une hydrogénation en présence d’un catalyseur métallique hydrogénation et d’hydrogène de manière à obtenir un flux contenant de l’éthylène glycol (HOCH2CH2OH).
