(EN) PROCESS AND CATALYST FOR THE PREPARATION OF ALDONIC ACIDS
(FR) PROCEDE ET CATALYSEUR DE PREPARATION D'ACIDES ALDONIQUES
Abrégé
(EN)
This invention relates to a process for the preparation of aldonic acids (in particular gluconic acid) by oxidation of aldoses with oxygen or with a gas containing oxygen, in the presence of supported bimetallic catalysts based on gold and platinum.
(FR)
L'invention concerne un procédé de préparation d'acides aldoniques (notamment l'acide gluconique) par oxydation d'aldoses avec de l'oxygène ou avec un gaz qui contient de l'oxygène, en présence de catalyseurs bimétalliques à base d'or et de platine déposés sur un support.
