Abstract
Procédé de préparation du sulfamate d'ammonium par introduction d'anhydride sulfurique et d'ammoniac dans un autoclave renfermant une masse fondue essentiellement constituée de sulfamate d'ammonium et d'imido-disulfonate d'ammonium. On maintient un rapport molaire de NH3 à SO3 allant de 1,5 à 1,99 et on ne chasse pas de l'autoclave les gaz qui se rassemblent au-dessus de la phase fondue. On supprime ainsi les difficultés qu'entraînerait l'obstruction des conduites par lesquelles l'ammoniac s'échappait.
