Cyclohexanecarboxylic acid is the organic compound with the formula C₆H₁₁CO₂H. It is the carboxylic acid of cyclohexane. It is a colorless oil that crystallizes near room temperature.[1]

Preparation and reactions

It is prepared by hydrogenation of benzoic acid.

Cyclohexanecarboxylic acid is a precursor to the nylon-6 precursor caprolactam via its reaction with nitrosylsulfuric acid. It can also be oxidized to cyclohexene.[1]

Cyclohexanecarboxylic acid exhibits the reactions typical of carboxylic acids, including its conversion to the acid chloride cyclohexanecarbonyl chloride.[2][3]
