Title
(EN) PROCESSES FOR THE PRODUCTION OF XYLITOL
(FR) PROCEDES DE PRODUCTION DE XYLITOL
Abstract
(EN)
Methods of producing xylitol comprising the oxidative decarboxylation of a reactant substrate are provided herein. The oxidative decarboxylation is performed in one of two ways. In the first, the oxidative decarboxylation is performed by an electrochemical process, preferably an anodic odixative decarboxylation of a reactant substrate. In the second, the oxidative decarboxylation of the reactant substrate is carried out by a series of oxidation-reduction chemical reactions.

La présente invention concerne des procédés de production de xylitol par décarboxylation oxydative d'un substrat réactant. Cette décarboxylation oxydative se pratique de deux façons. La première est une voie électrochimique, de préférence une décarboxylation oxydative anodique d'un substrat réactant. La seconde fait intervenir une série de réactions chimiques d'oxydoréduction.
