FIELD: industrial organic synthesis. ^ SUBSTANCE: invention provides improved process for production of adipic acid finding use in various fields, e.g. as various product additives, in manufacture of concrete, and as monomer in polymer production. Process consists of oxidizing cyclohexane with oxygen or oxygen-containing gas in presence of solvent based on lipophilic-type monocarboxylic acids containing 7 to 20 carbon atoms and oxidation catalyst, wherein thus formed esters' hydrolysis stage is accomplished by treating reaction medium before extraction of carboxylic acids or treating organic phase obtained from reaction medium after extraction of formed adipic acid, which treatment consists in adding strong acid to medium to be treated, said medium being maintained at temperature above 50°C. ^ EFFECT: weakened unfavorable effect of esters formed in the process. ^ 16 cl, 5 ex |
