Benzene and cyclohexane separation using 1-propanenitrile-3-butylimidazolium dicyanamide ionic liquid

Cyclohexane is mainly produced by catalytic hydrogenation of benzene, and the separation of unreacted benzene is very important process. However, the separation of benzene and cyclohexane mixture is one of the difficult separation processes in petrochemical industry. Presently, extractive distillati...
