2]O at the boiling point of the azeotropic mixture is a function of the apparent "volatility" of water in the mixture.
When separation is very difficult because the components of a mixture have almost identical volatilities, improvement can be made by adding a different component which is soluble in the mixture or which forms a constant boiling or azeotropic mixture with one or more of the original ingredients, thus permitting greater ease of separation.
In addition, when water is combined in an azeotropic mixture with certain solvents the evaporation can be accelerated.
