what is fractional distillation

Distillation is used for separating the constituents of a liquid mixture, which differ in their boiling points. Depending upon the difference in the boiling points of the constituents, different types of distillation like fractional distillation, steam ..

This liquid air contains two main substances, nitrogen and oxygen in liquid forms whose boiling points are -196 o C and -183 o C respectively. So when this liquid air is allowed to warm up, nitrogen with low boiling point boils over first and is separated. What remains behind is liquid o..

It is used for separating two liquids in any mixture, which have boiling points within a narrow range of temperatures. In such cases, simple distillation does not give complete separation and a modified version called fractional distillation is employe..

The outgoing hot vapors from the main iron still preheat coal tar obtained from the destructive distillation of coal, in a pre-heater. In this process, coal tar loses most of the water it contains, along with some low boiling hydrocarbons. It is then sent to the main iron still (a side r..

Distillation - This method is used to purify liquids that boil without decomposition and have non-volatile impurities. Impure liquid is boiled and the resulting vapors are condensed to get the pure liqu..

The digested reaction mixture, on cooling, is transferred to a round bottomed distillation flask, and distilled with a concentrated alkali solution (NaOH). Ammonia produced is absorbed in a known volume of HCl solution of a known strength...

This method is used to purify liquids that boil without decomposition and have non-volatile impurities. Impure liquid is boiled and the resulting vapors are condensed to get the pure liqu..

It is used for separating liquids having boiling points differing by 10-20 degrees. The liquid having the lower boiling point distills over first, and the other liquid component is left behind. In this process, vaporization and condensation occur side by sid..
