Definition of adipic acid in English:

adipic acid

nounəˈdɪpɪkəˌdipik ˈasid

mass nounChemistry

A crystalline fatty acid obtained from natural fats and used especially in the manufacture of nylon.
〔化〕脂肪酸
Alternative name: hexanedioic acid; chemical formula: HOOC(CH₂)₄COOH
Example sentencesExamples
- W. H. Carothers of E. I. DuPont de Nemours first produced nylon in 1931 from hexamethylenediamine and adipic acid, a six-carbon amine and a six-carbon acid.
- For example, polyesters are created by the reaction of a dihydric alcohol, such as ethylene glycol, which contains two hydroxyl groups and a diacid, like adipic acid, containing two carboxyl groups.
- Nylon 66 is a polyamide based on hexamethylene diamine and adipic acid.
- The last step of adipic acid synthesis involves nitric acid oxidation, resulting in the formation of nitrous oxide as a byproduct.
- When adipic acid is manufactured from petroleum, huge amounts of ozone depleting nitrous oxide, N 2 O, are produced.

Origin

Mid 19th century: from Latin adeps, adip- 'fat' (because the acid was first prepared by oxidizing fats) + -ic.
