Abstract

Procédé de distillation par extraction à l'acétonitrile d'hydrocarbures en C5 . Dans la distillation par extraction des hydrocarbures en C 5 ayant des degrés d'insaturation différents, utilisant l'acétonitrile, une augmentation de la sélectivité de l'acétonitrile est obtenue en ajoutant à l'acétonitrile de faibles quantités d'au moins un composé tel que le diméthylformamide, le diméthylsulfoxyde, la morpholine, le furfural, la N-méthylpyrrolidone, le 3-méthoxypropionitrile, la gamma-butyrolactone, l'éther monométhylique de l'éthylène glycol, l'éther monométhylique du diéthylène glycol, l'éther monoéthylique de l'éthylène glycol et l'éther monoethylique du diéthylène glycol. Obtention d'isoprène pur à 99 %.
