Analytically GLC is the best (Gas chromatography)
In a productive way distillation is prominent.
In fractional distillation, the substances in a mixture are heated to their boiling points. Different substances have different boiling points, so will be separated at different times. The answer to your question is simply because they have different boiling points.
Distillation
Using distillation
Separation is possible by distillation because boiling points are different.
you can put the mixture in a pot and put the temperature as the boiling point of the one that has the lowest boiling point.
To separate substances (that have different boiling points).
Distillation can be used to separate solutions of miscible liquids, because the liquids have different boiling points. Distillation works because it vaporizes the more volatile of the two liquids.
distillation is used to separate solutions of different boiling points though often complete separation of solutions can't be achieve due to azotrops example - when separating water and ethanol the fluid with the highest boiling point is ~97% ethanol ~3% water due entropic considerations

Distillation
Using distillation
Distillation is based on the differences of boiling points of substances.
The process of separation is called distillation.
Different liquids boil at different temperatures. When the boiling points (the temperature at which a liquid boils) are sufficiently different, boiling can be used to seperate the liquids
Separation is possible by distillation because boiling points are different.
Simply heat the mixture. Given that they have different boiling points, one will evaporate before the other and thus you will have two separate substances
you can put the mixture in a pot and put the temperature as the boiling point of the one that has the lowest boiling point.
