Absolute alcohol or dehydrated alcohol is anhydrous pure ethanol, ( C₂ H₅ OH) containing no more than one percent water.

It is not possible to obtain absolute alcohol by simple fractional distillation, because a mixture containing at least 95.4% alcohol and 5.6% water becomes a constant boiling mixture (an azeotropic mixture). To obtain 100% pure alcohol a small quantity of benzene is added to rectified spirit and the mixture is then distilled. Absolute alcohol is obtained in third fraction that distills over at 351.3° K (78.2° C).

There is also an absolute alcohol production process by dehydrationDehydration is the removal of water ( Greek hydros from an object. There are many methods of dehydration, with the most common being the application of dry heated air. This causes evaporation of the surface water, which is replaced by water internally. using glycerineGlycerine, Glycerin or Glycerol (CHO is an alcohol (hence the name glycerol with three hydroxyl groups (OH): H H H CH-OH | | | | H C C C H or CH-OH | | | | OH OH OH CH-OH Other synonyms of glycerine are 1,2,3-propanetriol; D-glycerol; L-glycerol (although.
