Abstract
L'invention concerne un procédé pour la préparation d'acide cyanurique moyennant le chauffage d'une solution d'urée et/ou de biuret dans un solvant organique polaire. Le procédé selon l'invention est caractérisé en ce qu'on exécute la réaction en présence d'un nitrate d'ammonium, de métal alcalin et/ou de métal alcalino-terreux qui est dissous dans le mélange réactionnel. Le procédé selon l'invention peut être utilisé pour la préparation d'acide cyanurique ayant une terreur en ammélide et en amméline considérablement réduite.
