설명

일반 설명

Cyclohexane is a cyclic alkane that predominantly exists in chair conformation due to higher stability.[1] It participates as starting reagent in the photonitrosylation process (PNC process) and affords ε-caprolactum.[2] Its oxidation by employing various oxidants such as hydrogen peroxide, tert-butyl hydroperoxide and molecular oxygen has been reported.[3]

애플리케이션

Cyclohexane has been used in the following studies:

• As a solvent in the synthesis of europium dibenzoylmethide triethylammonium (EuD₄TEA).[4]
• Preparation of poly(dimethylsiloxane) (PDMS) microchip.[5]
• As a solvent in the two-solvent (cyclohexane/water) deposition method for the preparation of monometallic 5wt% Ni containing catalysts.[6]

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.[7]
