Title (EN) OXIDATION OF URONIC ACIDS TO ALDARIC ACIDS
(FR) OXYDATION D'ACIDES URONIQUES EN ACIDES ALDARIQUES
Abstract:
(EN) Disclosed is the oxidation of uronic acids, such as galacturonic acid, to the corresponding aldaric acids, such as galactaric acid, under neutral or acidic conditions. Use is made of a supported gold catalyst. The oxidation occurs in good selectivity and yield, under unexpectedly mild conditions. A source of galacturonic acids is pectins, such as from sugar beet pulp.
(FR) La présente invention concerne l'oxydation d'acides uroniques, comme l'acide galacturonique, en acides aldariques correspondants, comme l'acide galactarique, dans des conditions neutres ou acides. Un catalyseur à l'or supporté est utilisé. L'oxydation se produit avec une bonne sélectivité et un bon rendement, dans des conditions étonnamment modérées. Les pectines, issues par exemple de la pulpe de betterave, sont des source d'acides galacturoniques.
