By heating the mixture to the right temperature, the alcohol will evaporation and leave the water behind. However, alcohols and water are quite difficult to separate completely, and the separation will not be 100% by this method. See the Re...

this is a mixture, called a solution. you could place this mixture into a distiallation apparatus and use the difference in boiling points to separate them. the alcohol has a much lower BP, probably in the range of 50 to 70 centigrade (look...

So you could use the filtering and evaporation trick to separate them using petroleum spirit instead of water. But if you do that, the products might not be safe to use as food. There might be a lasting taint from the petroleum spirit even after it had all evaporated (because of impurities that would not evaporate).

So why does alcohol, with a molecular wt of 46, freeze at a lower temperature than water, which has a molecular wt of 18? Another factor comes into play. This factor is called hydrogen bonding. It causes an increased attraction between molecules which makes them harder to separate(or put into motion).

Normally by distillation. By heating the mixture up the alcohol will vaporize first, leaving the water in the container. The vapor that comes off can be re-condensed to obtain the alcohol.

Whisky consists primarily of water and alcohol. Other constituents (usually < 1%) in the whisky are ... Why does high proof whisky become warm when diluted with water? The OH groups of ethanol form hydrogen bonds with the water molecules. The bonded molecules are in a lower energy state than the separate molecules.

THE differential solubility of sulfur in ethanol and water could be exploited to separate ethanol from water. ... The proposed alcohol/water separation process could be exploited industrially to produce clean fuel from fermented vegetable matter. In one version of this concept, sulfur would be added to an ethanol/water mixture:
