What do you mean by Fractional Distillation?
Answers
❖ 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:
Fractional distillation is a process by which individual components can be separated using heat from a given mixture.
The boiling points of each component in the mixture determine the order of separation.
Common uses of fractional distillation include the production of distilled water, and gasoline from crude oil.
