Radioactive adipic acid was fed to fasted experimental rats and the metabolic products identified in the urine were urea, glutamic acid, lactic acid, beta-ketoadipic acid, and citric acid.The presence of beta-ketoadipic acid provided some evidence that adipic acid is metabolized by beta-oxidation in much the same fashion as fatty acids. Cyclohexene is oxidized with hydrogen peroxide using a tungstate-based catalyst and a phase transfer catalyst. The general molecular formula for dicarboxylic acids can be written as HO2C−R−CO2H, where R can be aliphatic or aromatic.
