CA 2257347

The invention discloses a method for purifying adipic acid in water. More precisely it discloses an improvement in adipic acid crystallization or recrystallization in water, characterised in that the said crystallization or recrystallization is effected in presence of a strong proton acid and/or in the presence of carbon monoxide. This crystallization or recrystallization particularly enables the content of metal catalyst traces in the adipic acid to be reduced.

La présente invention concerne un procédé de purification de l'acide adipique dans l'eau. Plus précisément elle concerne un perfectionnement à la cristallisation ou à la recristallisation dans l'eau de l'acide adipique, caractérisé en ce que ladite cristallisation ou recristallisation est effectuée en présence d'un acide protonique fort et/ou en présence de monoxyde de carbone. Cette cristallation ou recristallisation permet en particulier de réduire la teneur de l'acide adipique en traces de catalyseur métallique.
