What is the use of adipic acid?
Almost all adipic acid is used as a comonomer with hexamethylenediamine to produce nylon 6-6. It is also used to manufacture other polymers such as polyurethanes.
Is adipic acid toxic?
Adipic acid caused no developmental toxicity in mice, rats, rabbits, or hamsters when administered orally. Adipic acid is partially metabolized in humans; the balance is eliminated unchanged in the urine. Adipic acid is slightly to moderately toxic to fish, daphnia, and algae in acute tests.

What happens when adipic acid is heated?
When adipic acid is heated, cyclopentanone is obtained. It contains one carbon atom less than adipic acid which indicates decarboxylation. Also, a molecule of water is lost which results in cyclization.
Is adipic acid environmentally friendly?
