A method for manufacturing an alkanedicarboxylic acid by oxidizing cycloalkanol and/or cycloalkanone with an aqueous solution of nitric acid, which comprises using an adiabatic reactor comprising a feed nozzle enabling to feed cycloalkanol and/or cycloalkanone at a linear velocity not lower than 8 x 10-2 m/sec and a mixing apparatus.
L'invention concerne un procédé de production d'un acide alcanedicarboxylique par oxydation d'un cycloalcanol et/ou d'un cycloalcanone à l'aide d'une solution d'acide nitrique aqueuse. Ce procédé consiste à utiliser un réacteur calorifugé comprenant une tuyère d'alimentation au moyen de laquelle le cycloalcanol et/ou le cycloalcanone est alimenté à une vitesse linéaire d'au moins 8x10<-2>m/sec, et un mélangeur.
