Abstract

L'invention concerne l'obtention continue d'acide di- et/ou trichlorocyanurique. On fait réagir du chlore avec du cyanurate disodique et/ou du cyanurate trisodique en milieu aqueux, en soumettant le mélange réactionnel à l'action d'un agitateur à vitesse réglable, dont l'intensité est notamment fonction du débit de la solution d'alimentation en cyanurate disodique et/ou trisodique. Ce procédé permet d'augmenter de façon reproductible les dimensions moyennes des cristaux du produit.
