Title
(EN) METHODS FOR THE ELECTROLYTIC PRODUCTION OF ERYTHROSE OR ERYTHRITOL
(FR) procEDES pour la production Electrolytique D'Erythrose ou d'Erythritol
Abstract
(EN)
Methods for the production of erythrose and/or erythritol are provided herein. Preferably, the methods include the step of electrolytic decarboxylation of a ribonic acid or arabinonic acid reactant to produce erythrose. Optionally, the reactant can be obtained from a suitable hexose sugar, such as allose, altrose, glucose, fructose or mannose. The erythrose product can be hydrogenated to produce erythritol.
(FR)
La présente invention concerne des procédés pour la production d'érythrose et/ou d'érythritol. De préférence, les procédés comprennent l'étape de décarboxylation électrolytique d'un réactif à base d'acide ribonique ou d'acide arabinonique afin de produire de l'érythrose. De manière facultative, le réactif peut être obtenu à partir d'un sucre hexose adapté, tel que l'allose, l'altrose, le glucose, le fructose ou le mannose. L'érythrose peut être hydrogéné pour produire de l'érythritol.
