Abstract

L'invention concerne un procédé perfectionné de production du sel trisodique de l'acide carboxyméthyloxy-succinique par réaction en milieu aqueux d'acide maléique et d'acide glycolique dans des conditions basiques en presence d'ions de zinc ou de métal alcalino-terreux. Le sel de zinc ou de métal alcalino-terreux d'acide carboxyméthyloxy-succinique formé est ajouté progressivement à un carbonate de métal alcalin. Le produit obtenu par le procédé de l'invention peut être utilisé comme adjuvant améliorant le pouvoir de détergence de formulations détergentes.
