Title (EN) PREPARATION AND SEPARATION OF A DICARBOXYLIC ACID-CONTAINING MIXTURE USING A DICARBOXYLATE FORM OF AN ANION EXCHANGE CHROMATOGRPAHY RESIN
(FR) PRÉPARATION ET SÉPARATION D'UN MÉLANGE CONTENANT UN ACIDE DICARBOXYLIQUE
Abstract:
(EN) Processes for separating a di-carboxylic acid or salt thereof from a mixture containing the di-carboxylic acid or salt thereof and one or more other components are provided. Also separation media useful for these separation processes is provided. In particular, processes for preparing an aldaric acid are described, such as glucaric acid from glucose, which includes separating the aldaric acid from the reaction product. Also, various glucaric acid products are described.
(FR) L'invention concerne des procédés de séparation d'un acide dicarboxylique ou un sel de celui-ci à partir d'un mélange contenant l'acide dicarboxylique ou son sel et un ou plusieurs autres composants. L'invention concerne également des milieux de séparation utiles pour ces procédés de séparation. En particulier, elle concerne des procédés de préparation d'un acide aldarique, comme l'acide glucarique à partir du glucose, qui comprend la séparation de l'acide aldarique à partir du produit de réaction. L'invention concerne également divers produits d'acide glucarique.
