Adipic acid, also known as fatty acid, is an important organic dibasic acid with the chemical formula HOOC(CH2)4COOH. Adipic acid has high reactivity, can be salt reaction, esterification reaction, amidation reaction, and can be condensed with diamine or diol to form polymer.
Basic properties
Adipic acid is a white crystalline powder, with a melting point of about 152-154°C, a boiling point of 330.5°C (decomposition), and a density of about 1.36 g/cm³.12 It is less soluble in water, but dissolves better in alcohols, ethers, and hot water.23 Adipic acid has the general properties of dibasic acids, and can be esterified to form mono- or diesters, and when heated above 300°C, it decarboxylates to form cyclopentanone.
