The process of separating the component substances from
liquid mixture is known as distillation.
The process who has different boiling points after the
separation of chemical mixture is known as fractional distillation. In this
process, the mixture is boiled in a round flask, where vapors of the boiling
solution pass along the column in fractions. At the top, the temperature is the
coolest and at the bottom, it increases down. Then the components with higher
boiling points reduce on the column when it turns to the solution. On the other
hand, the components with lower boiling points further pass and are collected.
This process is used for separating mixtures like, water,
curd oil etc.
