Abstract

L'invention concerne l'industrie de la chimie organique. Elle a pour objet un procédé de préparation d'une suspension aqueuse d'un composé azoïque insoluble dans l'eau, suivant lequel on mélange de manière continue, dans une zone de réaction 11 d'où l'on soutire la suspension de manière continue, un premier courant 13 contenant un composé diazoïque résultant de la diazotation d'une amine hétérocyclique ou benzénoïde faiblement basique dans un milieu acide, appelé ci-après constituant diazoïque, avec un second courant 25 contenant un composé capable de copulation avec le constituant diazoïque dans les conditions régnant dans la zone de réaction pour la formation d'un composé azoïque insoluble dans l'eau et appelé ci-après constituant de copulation. Ce procédé est appliqué par préférence à la production de colorants azoïques dispersés.
