Solution

Chloroform (b.p. $334 \mathrm{~K}$ ) and aniline (b.p. 457) are easily separated by the technique of distillation as both the liquids having sufficient difference in their boiling points. - The fractions of crude oil in petroleum industry is separated using fractional distillation due to less difference in boiling points of liquids. - Glycerol can be separated from spent-dye using distillation under reduced pressure. - Aniline is separated by steam distillation from aniline-water mixture.
