Adipic acid (GOST 10558-80):
Adipic acid HOOC(CH2)4COOH is white crystalline substance. It possesses all chemical properties of carboxylic acids. It forms salts most of which are soluble in water. It easily esterifies into monoesters and diesters.
In reaction with glycols adipic acid forms polyesters. Adipic acid salts and esters are called adipinates.
Adipic acid is used for production of: hexamethylenediammoniumadipinate (ag-salts), hexamethylenediammoniumsebacinate (sg-salts), adipic acid esters, polyurethanes, plasticizers, lubricants.
