General description

Cyclohexane is a cyclic alkane that predominantly exists in chair conformation due to higher stability.

Application

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.

Other Notes

The article number 227048-4X2L will be discontinued. Please order the single bottle 227048-2L which is physically identical with the same exact specifications.
