Abstract

L'invention concerne un procédé de préparation d'alkylphosphines de formule générale suivante : Rn PH3-n (1) Selon l'invention, on fait réagir de l'hydrogène phosphoré, des phosphines primaires ou secondaires avec des alkylamines de formule générale suivante : Rn NH3- n (II) dans des rapports molaires de 0,1 à 10 moles d'alkylamine de formule II par mole d'hydrogène phosphoré ou de phosphine, à 150-400 degrés C sous une pression allant de la pression normale à 1 atmosphère relative. On effectue la réaction en présence de catalyseurs et on fait passer les matières de départ dans une zone de réaction à une vitesse assurant une durée de contact de 0,1 à 400 s entre ces dernières et le catalyseur.
