Cyclohexane, a cycloalkane, is a combustible liquid with petrol like odor. It can be synthesized by hydrogenation of benzene in the presence of nickel or platinum catalysts. Cyclohexane is the precursor for the synthesis of polyamides. Cyclohexane ring forms the structural unit of many naturally occurring products. The conformational changes of cyclohexane have been investigated over the temperature range of 100-1200°C. Conversion of cyclohexane to cyclohexanol and cyclohexanone, via oxidation in the presence of Cu-nanoclusters anchored on nanocrystalline Cr2O3 has been reported.
Application
Cyclohexane has been used to prepare iodine solution for analyzing the influence of vibrational relaxation of I2 molecules on structure using picosecond X-ray liquidography.
