Aniline and water form an immiscible mixture. Which technique is most suitable for separating aniline from this mixture?

1. Steam distillation
2. Fractional distillation
3. Simple distillation
4. Distillation under reduced pressure

Correct answer: Steam distillation

Solution

Aniline (bp 184 deg C) is immiscible with water and would decompose near its boiling point. Steam distillation lets it co-distil with steam at about 98 deg C, well below its normal boiling point, without decomposition.
