The Reactions of Adipic acid
Adipic acid is a white crystalline powder. This organic compound is the most important synthetic
dicarboxylic acid annually produced, mainly used as a precursor for the production of nylon.
Adipic acid is also used in the chemical industry to produce other polymers, coatings, plasticizers
and detergents.
1. Preparation and reactivity
Adipic acid is produced from a mixture of cyclohexanol and cyclohexanone called "KA oil", the
abbreviation of "ketone-alcohol oil." The KA oil is oxidized with nitric acid to give adipic acid,
via a multistep pathway. Early in the reaction the cyclohexanol is converted to the ketone,
releasing nitrous acid:
HOC6H11 + HNO3 → OC6H10 + HNO2 + H2O
Among its many reactions, the cyclohexanone is nitrosated, setting the stage for the scission of the
C-C bond:
HNO2 + HNO3 → NO+NO3- + H2O
OC6H10 + NO+ → OC6H9-2-NO + H+
Side products of the method include glutaric and succi
