Azeotropy
Definition
A remarkable physicochemical thermodynamic phenomenon characteristic of certain liquid mixtures, consisting in their property to boil at a constant and fixed temperature, generating vapors with a structural composition identical to that of the liquid phase. This phenomenon prevents the separation of components via classical fractional distillation, defining the formation of a minimum or maximum point on the vapor pressure curve and requiring the implementation of specialized separation techniques in chemical engineering.
