what do you mean by fractional distellation
Asked by Akashpatil | 8th Aug, 2014, 07:32: PM
The fractional distillation is a separation technique which is used to separate mixture of liquids. When liquids in mixture have boiling points which are nearby are separated by using fractionating column.
In this type, mixture is boiled in a round bottom flask and the vapours are allowed to pass through fractionating column. The column is coolest at the top and warmer at the bottom. Vapours of the Liquids with higer boling points, raises into the column, gets cooled and come back to solution in the round bottom flask. While vapours of the liquids with lower boiling points raises and further pass through the column, condensed and collected in the another flask.
