Abstract

Procédé de fabrication d'acides carboxyliques à partir de nitriles. On fait réagir le nicotinonitrile ou un produit d'hydrolyse intermédiaire de celui-ci, ou bien un nitrile aromatique avec un ou plusieurs groupes cyano sur un noyau benzénique ou naphtalenique, ou un produit d'hydrolyse intermédiaire d'un tel nitrile, avec de l'eau en phase vapeur en présence d'un catalyseur acide solide pour former un effluent gazeux contenant l'acide carboxylique correspondantProcess for the manufacture of carboxylic acids from nitriles. Nicotinonitrile or an intermediate hydrolysis product thereof, or an aromatic nitrile with one or more cyano groups on a benzene or naphthalene ring, or an intermediate hydrolysis product of such a nitrile, is reacted with water in the vapor phase in the presence of a solid acid catalyst to form a gaseous effluent containing the corresponding carboxylic acid
