Azeotropic distillation

Vedclass · Answer

(C) Rectified spirit contains approximately $95.6\%$ ethanol and $4.4\%$ water by mass,which forms a constant boiling mixture known as an azeotrope. Since simple fractional distillation cannot separate the components of an azeotrope,azeotropic distillation is used. In this process,a third component like benzene is added to break the azeotrope,allowing the production of absolute alcohol ($100\%$ pure ethanol).

The process of manufacture of absolute alcohol from rectified spirit is:
