Abstract

L'invention concerne un procédé pour préparer des polyamines à partir de polynitriles avec un catalyseur d'hydrogénation en pastilles. On hydrogène des polynitriles en présence d'un catalyseur en pastilles, en présence d'une polyamine ou d'une hydroxylamine ne comportant pas plus de quatre atomes de carbone entre les radicaux amino ou entre les radicaux amino et hydroxy. L'invention s'applique en particulier à l'hydrogénation de la N,N'-bis(cyanoéthyl) éthylènediamine ou d'oxypolynitriles en présence de catalyseurs au cobalt en pastilles dont la désintégration est évitée.
