Adipic Acid. 
Adipic Acid is an organic chemical compound of formula HOOH(CH2)4COOH. It is near important industrial dicarboxylic acid: About 2.5 meg tonnes are produced annually yesteryear the industry, mainly every bit a precursor chemical compound for the production of nylon.Otherwise, this acid is rare inwards nature.
Preparation Of Adipic Acid.
Adipic acid is prepared industrially yesteryear : (1) Oxidation of cyclohexane amongst air inwards the presence of boric acid catalyst to hand cyclohexanol ; (2) Oxidation of cyclohexanol amongst concentrated nitric acid to shape cyclohexanone together with thus adipic acid.
The cyclohexane needed for the higher upwardly procedure is obtained yesteryear the catalytic hydrogenation of benzene.
Properties of Adipic Acid.
Adipic acid is white crystalline solid, mp 153°C. it is slightly soluble inwards water, only soluble inwards alcohol together with ether. It gives all the normal reactions of a dicarboxylic acid.
When heated to 300°C, it yields cyclopentanone.
When adipic acid is heated amongst hexamethylenediamine, a polyamide Nylon-6,6 is formed yesteryear splitting out H2O molecules.
Uses of Adipic Acid.
Adipic acid is used for the manufacture of.
- Nylon together with polyurethane foams.
- esters used every bit plasticisers together with lubricants.
