Simple distillation

Vedclass · Answer

(B) $n$-Pentane (boiling point $\approx 36 \ ^\circ C$) and toluene (boiling point $\approx 111 \ ^\circ C$) are miscible liquids with a significant difference in their boiling points. Simple distillation is used to separate liquids that have a difference in boiling points of more than $20-25 \ K$ and are stable at their boiling temperatures. Since the boiling point difference between $n$-pentane and toluene is large,simple distillation is the suitable method for their separation.

Which one of the following methods is suitable to separate a mixture of $n$-pentane and toluene?
