Title (EN) NEW METHOD FOR SYNTHESISING MUCIC ACID USING OZONE
(FR) NOUVELLE METHODE DE SYNTHESE DE L'ACIDE MUCIQUE PAR L'OZONE
Abstract:
(EN) The present invention relates to the use of ozone for the synthesis of mucic acid. More specifically, the invention relates to a synthesis method using ozone, by means of which a high yield of mucic acid can be obtained, which can be produced in crystalline form, without having to use either an organic solvent or a catalyst, and with moderate power consumption. Mono-, oligo- and/or polysaccharides comprising galactose units or galacturonic acid, and galacturonic acid in particular, can be used as the starting product.
(FR) La présente invention se rapporte à l'utilisation de l'ozone pour la synthèse de l'acide mucique. Un procédé de synthèse mettant en œuvre l'ozone permet d'atteindre un rendement élevé en acide mucique, qui peut être obtenue sous forme cristalline, sans qu'il soit nécessaire d'employer ni solvant organique ni catalyseur, et avec une consommation d'énergie modérée. Des mono-, oligo- et/ou polysaccharides comprenant des unités galactose ou acide galacturonique peuvent servir de produit de départ, et notamment l'acide galacturonique.
