Abstract
L'invention concerne un procédé pour la préparation d'acide cyanurique par chauffage d'urée et/ou biuret dissous dans un solvant Le procédé selon l'invention est caractérisée en ce qu'on effectue la réaction dans un solvant constitué d'un sel, de préférence un nitrate fondu d'un métal alcalin ou alcalinoterreux, ou un mélange de tels sels. De préférence le sel fondu contient en outre au plus 50 % poids de nitrate d'ammonium L'acide cyanurique peut être appliqué pour la préparation d'isocyanurates chlorés qui sont utilisables comme désinfectants et de résines synthétiques.
