Abstract
Alkane dicarboxylic acids are prepared by a continuous process wherein cycloalkanols, cycloalkanones, cycloalkylamines, o - hydroxyalkane carboxylic acids having at least four carbon atoms, lactones of such acids and/or tetrahydrofurane are oxidized by intensely mixing said organic reactant with a large excess of 40 to 70% by weight nitric acid, the reaction is allowed to proceed at atmospheric or superatmospheric pressure and a temperature of 20 DEG to 100 DEG C., after a residence period of less than four minutes the mixture leaving the reaction zone is freed from nitrous oxides, the concentration of nitric acid is restored by evaporation of water to a level which is approximately that of the reaction zone nitric acid concentration, the alkane dicarboxylic acid is separated by a conventional method from a minor portion of the reaction mixture, the mother liquor is united with the remainder of the reaction mixture, fresh nitric acid, if desired, is added to the mixture thus obtained and this mixture is intensely mixed with fresh initial organic material and returned to the reaction zone.
