Fractional distillation

Explanation

Fractional distillation : Fractional distillation for liquids that have B.Pt difference less than `40^(@)C.` The technique here is that vapours of liquid mixture. When pass through long fractionating column vapours of the liquid with high B.Pt condense and those with low B.Pt pass over through the condenser get condensed and collected in the receiver. Here, long tubes having different shapes and designs to fit for particular requirements are used. These are called fractionating columns. The liquid mixture is taken in a distillation flask i.e., fitted with a fractionating column at its mouth. At the upper end of the column, there is a provision to connect it to the water condenser.
