Cyclohexane Manufacture

Cyclohexane is a relatively stable cycloalkane, present in crude oils in concentrations of 0.1–1.0%. This cycloparaffin is a colorless, flammable liquid, widely used as an intermediate in nylon manufacturing. On a commercial scale, cyclohexane production is almost entirely based on the catalytic hydrogenation of benzene, which can be conducted in the liquid or vapor phase in the presence of hydrogen.

Technology Description

The following paragraphs describe a process for the production of cyclohexane from benzene and hydrogen that involves liquid-phase hydrogenation of benzene in the presence of a nickel-based catalyst.
