Abstract
Process for the production of adipic acid by reaction of cyclohexanol and/or cyclohexanone with an aqueous solution of nitric acid of concentration between 40 and 65% by weight, preferably between 45 and 55%, in two reactors, in the first of which soluble intermediate oxidation products are formed operating at temperatures lying between 30 and 80 degree C, preferably between 35 and 50 degree C, while in the second, at temperatures between 85 and 110 degree C, preferably between 90 and 95 degree C, the oxidation of the intermediates to adipic acid is completed in presence of a catalyst based on pentavalent vanadium, assisted by copper ions.
