Question

How can we separate Benzene and toluene?

Answer 1

Fractional distillation:-

• The type of distillation where separation of miscible liquids is been done is called fractional distillation.
• This process here involves repeated distillations and condensations, and generally, the mixture is separated into its component parts.
• When the mixture is heated at a certain temperature where fractions of the mixture start to vaporize, at that moment the separation happens.

Separation of Benzene and Toluene:-

• Since the difference in their boiling points is very little, we can separate Benzene and Toluene by fractional distillation.
• The boiling point of benzene is $80.1°\mathrm{C}$ and the boiling point of toluene is $110.6°\mathrm{C}$.
• As a result of this Benzene first gets vaporized and condensed, and then it is collected
• Thus in this way, the two miscible liquids are separated.

Therefore, Benzene and Toluene can be separated through fractional distillation.
