Question

What do you mean by Fractional Distillation?

Answer 1

❖ Fractional Distillation :

❱ It is the process used for the separation of a mixture of two or more liquids that have different boiling points.

❱ Fractional distillation is carried out by using a fractionation column. In order to carry out the fractional distillation, we require a distillation flask, fractional column, Liebig condenser and a receiver.

❮ Activity ❯

➲ To separate the components of miscible liquids by Fractional Distillation.

⚫ Set up the apparatus.

⚫ Take the benzene and toluene liquids in the distillation flask.

⚫ Heat the mixture slowly.

⚫ Collect the first fraction in the receiver.

⚫ Collect the second fraction also into another receiver.

⚫ Keep close watch at the thermometer while distillation flask is being heated.

⚫ Which of the two liquids distillates first.

Answer 2

Answer:

Separation process in which the volatile components (having different boiling points) of a mixture (such as crude oil) are split from one another by heating the mixture in a column and collecting and condensing the vapors drawn from different levels of the column.
