Answer
Types of Distillation and Their Applications
- Simple distillation separates chloroform (61°C) and aniline due to their wide boiling point gap.
- Fractional distillation is used in the petroleum industry to separate components of crude oil.
- Distillation under reduced pressure is used to obtain high-boiling glycerol from spent-lye without decomposition.
- Steam distillation is used to remove aniline–water mixtures, as aniline becomes steam-volatile.
