Adipic Acid
Adipic acid is the organic compound with the formula (CH2)4(COOH)2. From the industrial perspective, it is the most important dicarboxylic acid: About 2.5 billion kilograms of this white crystalline powder are produced annually, tmainly as a precursor for he production of nylon . Adipic acid otherwise rarely occurs in nature.
Uses:
By far the majority of the 2.5 billion kg of adipic acid produced annually is used as monomer for the production of nylon by a polycondensation reaction with hexamethylene diamine forming 6,6-nylon.Other major applications also involve polymers: it is a monomer for production of Polyrethane and its esters are plasticizers , especially in pvc.
