11. It is the potassium salt of adipic acid . 12. It is the sodium salt of adipic acid . 13. Chemically, it is an ester of adipic acid . 14. It is the ammonium salt of adipic acid . 15. With the carboxylate groups separated by four methylene groups, adipic acid is suited for intramolecular condensation reactions. 16. Adipic acid , HOOC-( CH 2 ) 4-COOH, is not an aldaric acid, though it is structurally similar.17. Adipic acid otherwise rarely occurs in nature.18. Cyclohexane is mainly used for the industrial production of adipic acid and caprolactam, which are precursors to nylon. 19. It has been used as a precursor of adipic acid en route to nylon by a rhenium-catalyzed deoxydehydration reaction. 20. The final products after successive oxidations include succinic acid, which can enter the citric acid cycle, and adipic acid .
