Abstract

Procédé de neutralisation de produits réactionnels basiques dont l'utilisation technique nécessite l'addition de dispersifs. Il consiste à ajouter un acide tensio-actif libre, non additionné de substances basiques après sa préparation ou additionné de telles substances jusqu'à un pH égal à 3 seulement Application, par exemple à la neutralisation de colorants azoïques.
