A process for preparing dicarboxylic acids is described. More particularly a process is described for preparing adipic acid (1,6-hexanedioic acid), by the action of nitric acid, starting from cyclic ketones or alcohols which are the corresponding compounds from the standpoint of the number of carbon atoms, in the presence of one or more oxides of nitrogen at a molar concentration in the reaction mixture of greater than 2.5 mmol per kg of reaction mixture. |
