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.Process for obtaining pure pyridine-2-acetonitrile from the gaseous reaction product resulting from the action of cyanogen chloride on 2-methylpyridine in the gas phase, by abrupt cooling of the reaction product by means of a liquid, by neutralization and distillation, characterized in that liquid reaction product is used for the abrupt cooling and ammonia for the neutralization. Pyridine-2-acetonitrile is obtained in high yields and the unreacted 2-methylpyridine fractions are recycled simultaneously.
