· Over 98% of the cyclohexane produced is used to make nylon intermediates: adipic acid (60%), caprolactam, and hexamethylenediamine .
· It is used as a solvent for lacquers, resins and synthetic rubber.
· Cyclohexane is also used in manufacturing of solid fuel for camp stoves and and in fungicidal formulations (possesses slight fungicidal action).
· The industrial recrystallization of steroids also requires cyclohexane
