Abstract

a. Procédé de préparation de cyanates. b. On utilise un mélange réactionnel d'oxyde de carbone, d'un oxyde d'azote et une source d'hydrogène que l'on fait passer sur un catalyseur (10) d'hygrogénation pour préparer des cyanates. Les conditions réactionnelles choisies déterminent les quantités relatives des divers cyanates formés. c. Préparation du cyanate d'ammonium.
