Disclosed is a method for producing aminodihalophosphines, diaminohalophosphines, triaminophosphines, phosphite diamides, aminophosphines, diaminophosphines, phosphite amide halogenides, and aminophosphine halogenides by separating an acid in the presence of an auxiliary base. Said auxiliary base b) forms a salt with an acid, which is liquid at temperatures at which the valuable product is not significantly decomposed during separation of the liquid salt, and c) the salt of the auxiliary base and the valuable product or the solution of the valuable product form two immiscible phases in a suitable solvent.
L'invention concerne un procédé de fabrication d'aminodihalogénophosphines, de diaminohalogénophosphines, de triaminophosphines, d'ester-diamides d'acide phosphoreux, d'aminophosphines, de diaminophosphines, d'halogénures d'ester-amides d'acide phosphoreux et d'halogénures d'aminophoshines, avec élimination d'un acide et en présence d'une base auxiliaire, caractérisé b) en ce que la base auxiliaire forme, avec l'acide, un sel qui est liquide à des températures pour lesquelles le produit de valeur n'est pas décomposé de manière significative pendant le séparation du sel liquide et, c) en ce que le sel de la base auxiliaire forme, avec le produit de valeur ou avec la solution du produit de valeur dans un solvant approprié, deux phases liquides non miscibles.
