Abstract

Procédé pour l'obtention de pyridine-2-acétonitrile pur à partir du produit de réaction gazeux résultant de l'action de chlorure de cyanogène sur la 2-méthylpyridine en phase gazeuse, par refroidissement brusque du produit de la réaction au moyen d'un liquide, par neutralisation et distillation, caractérisé en ce qu'on utilise du produit de réaction liquide pour le refroidissement brusque et de l'ammoniac pour la neutralisation. On obtient le pyridine-2-acétonitrile avec des rendements élevés et on recycle simultanément les fractions de 2-méthylpyridine qui n'ont pas réagi.
