Cyclohexanecarboxylic acid is a precursor to the nylon-6 precursor caprolactam via its reaction with nitrosylsulfuric acid. It can also be oxidized to cyclohexene. [2] Cyclohexanecarboxylic acid exhibits the reactions typical of carboxylic acids, including its conversion to the acid chloride cyclohexanecarbonyl chloride. [3] [4]

Carboxylic acids tend to have higher boiling points than water, because of their greater surface areas and their tendency to form stabilized dimers through hydrogen bonds. For boiling to occur, either the dimer bonds must be broken or the entire dimer arrangement must be vaporized, increasing the enthalpy of vaporization requirements significantly.
Shikimic acid, biosynthetic precursor to aromatic amino acids, is a close relative of quinic acid. This substance was isolated for the first time in 1790 by German pharmacist Friedrich Christian Hofmann in Leer from Cinchona. [3] Its transformation into hippuric acid by animal metabolism was studied by German chemist Eduard Lautemann in 1863. [4]

Cyclohexane has two crystalline phases. The high-temperature phase I, stable between 186 K and the melting point 280 K, is a plastic crystal, which means the molecules retain some rotational degree of freedom. The low-temperature (below 186 K) phase II is ordered.
