Distillation of aniline/water mixture

Derrick S.  Follow

Can't we just distill the aniline off?

The boiling point of aniline is around 180 °C. Remember that water boils at 100 °C.

Do water and aniline mix?

Yes, but the solubility of aniline in water is rather low (around $\pu{30 g/l}$).

What's the advantage of the steam distillation?

Aniline and water form an azeotrope with a boiling point around 98 °C.

@AaronJohnSabu No, because the boiling point of the azeotrope is lower than that of water.More
