How are near-azeotropic blends identified

WebAn azeotrope is a mixture of compounds with the same composition in the vapour as in the liquid. In other words, an azeotrope is a liquid mixture that has a constant boiling point and whose vapour has the same composition as the liquid. Several compounds, such as toluene, benzene, and cyclohexane, form suitable azeotropes with water.
