Title (EN) SEPARATING AMMONIUM CHLORIDE FROM N-HYDROCARBYL(THIO)PHOSPHORIC TRIAMIDE
(FR) SEPARATION DE CHLORURE D'AMMONIUM DE TRIAMIDE N-HYDROCARBYL(THIO)PHOSPHORIQUE
Abstract:
(EN) A substantially anhydrous mixture which comprises ammonium chloride, the triamide, and ammonia is formed either by adding ammonia to a mixture of the other components or by conducting, in the presence of the ammonia and an organic solvent, a reaction to form the triamide and ammonium chloride as co-products. In all cases the ammonia is present in a sufficient excess amount relative to the ammonium chloride to form a separate liquid phase in which the ammonium chloride solids dissolve. Such separate liquid phase is separated from the remainder of said mixture.
(FR) L'invention concerne un mélange sensiblement anhydre renfermant du chlorure d'ammonium, un triamide et de l'ammoniac, formé soit par addition d'ammoniaque à un mélange constitué des autres composants, soit par provocation d'une réaction, en présence de l'ammoniac et d'un solvant organique, permettant de former des coproduits de triamide et de chlorure d'ammonium. Dans tous les cas, l'ammoniac est présent en quantité suffisante supérieure à celle de chlorure d'ammonium pour former une phase liquide séparée dans laquelle les solides de chlorure d'ammonium se dissolvent. Une telle phase liquide séparée est séparée du reste dudit mélange.
