Descripción

Descripción general

Cyclohexane is a cyclic alkane that predominantly exists in chair conformation due to higher stability. It participates as starting reagent in the photonitrosylation process (PNC process) and affords ε-caprolactum. Its oxidation by employing various oxidants such as hydrogen peroxide, tert-butyl hydroperoxide and molecular oxygen has been reported.

Aplicación

Cyclohexane has been used in the following studies:

• As a solvent in the synthesis of europium dibenzoylmethide triethylammonium (EuD₄TEA).
• Preparation of poly(dimethylsiloxane) (PDMS) microchip.
• As a solvent in the two-solvent (cyclohexane/water) deposition method for the preparation of monometallic 5wt% Ni containing catalysts.

Cyclohexane may undergo oxidation using hydrogen peroxide as oxidant and in the presence of a polyoxotungstate catalyst to form cyclohexanone and cyclohexanol as the main products. Its dehydrogenation in the presence of Ni-Cu/SiO₂ catalysts forms benzene in good yield.
