Studying the effect of using some additives on changing azeotropic behavior in distillation

Absolute ethanol is an important product required by industry. Azeotropic chemical mixture such as ethanol-water is impossible to break up to its original composition by simple distillation. The separation of azeotropic mixtures via distillation is quite complex because at the azeotrope condition, l...
