To get the benzene from hexane to use so-called "aromatization of hexane."This reaction occurs when the linear molecule of hexane into a "closed", with simultaneous cleavage of "excess" hydrogen atoms.The reaction proceeds as follows:

S6N14 = C6H6 + 4H2.

Prerequisite for the above reaction - high temperature (about 520-550 degrees), the pressure, the use of chromium catalysts or aluminum coated with a thin layer of these expensive materials such as platinum, containing additives other metals.
also received from hexane, benzene, and you can with the help of the dehydrogenation of cyclohexane.This reaction occurs in two stages.First of hexane, "cleavage" terminal hydrogens receive cyclohexane as follows:

S6N14 S6N12 = + H2.
then cyclohexane, by further dehydration, turn to benzene.The reaction is as follows:

S6N12 = C6H6 + 3H2.

Here too you need high temperature and the same pressure.Also use nickel catalysts.
As can be easily seen from the above methods, such reactions are feasible only in an industrial environment because it requires special equipment, withstand high temperatures and pressures.Not to mention the use of catalysts containing less expensive metal such as platinum.Therefore, to obtain in vitro benzene n-hexane as a raw material is not suitable.
