Description
Introduction:
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.
