Adipic acid is an important organic diacid, whose chemical formula is HOOC(CH2)4COOH. This material can generate salt formation reaction, esterification reaction, amidation reaction, and can be condensed with binary amine or dialcohol into high polymer. Adipic acid is an important binary carboxylic acid in industry, which plays an important role in chemical production, organic synthesis industry, medicine, lubricant manufacturing and other aspects. Its output ranks the second among all binary carboxylic acids.
