Abstract
L'invention concerne un procédé de récupération de la méthyldichlorophosphine pure à partir de mélanges constitués principalement par du trichlorure de phosphore et de la méthyldichlorophosphine par distillation en deux stades, où le trichlorure de phosphore et d'autres fractions à faible point d'ébullition sont chassés par distillation en tête du premier stade, tandis que la méthyldichlorophosphine pure est séparée des fractions à point d'ébullition élevé par distillation en second stade chargé du produit de fond du premier stade. L'invention est caractérisée en ce que, avant d'introduire le mélange dans le premier stade de distillation, on y dissout 0,01 à 1 % en poids d'un composé organique de baryum ou 0,1 à 10 % en poids d'un agent tensioactif non ionique et, avant d'envoyer le produit de fond du premier dans le second stade de distillation, on y ajoute 1-10 % en poids d'oxychlorure de phosphore.
