Question

Fractional distillation This method is used to separate the mixture of two miscible liquids where difference between their boiling points is less than 25 ºC. Also to separate a mixture of two or more miscible liquids for which the difference in boiling points is less than 25 K, fractional distillation process is used, for example, for the separation of different gases from air, different factions from petroleum products etc. The apparatus is similar to that for simple distillation, except that a fractionating column is fitted in between the distillation flask and the condenser. Based on the text above,and concepts you have learnt.what is the use of glass beads in fractionating column? ​

Answer 1

Fractional distillation is the separation of a mixture into its component parts, or fractions. Chemical compounds are separated by heating them to a temperature at which one or more fractions of the mixture will vaporize. It uses distillation to fractionate.

Answer 2

Answer:

Separation of a liquid mixture into fractions differing in boiling point (and hence chemical composition) by means of distillation, typically using a fractionating column is called fractional distillation. In other words, separation process in which the volatile components (having different boiling points) and the difference is less than 25 K of a mixture (such as crude oil) are split from one another by heating the mixture in a column and collecting and condensing the vapours drawn from different levels of the column.
