#phase equilibrium

• Azeotropic — Pertaining to azeotropy, regarding an azeotrope, or presenting the characteristics of a constant boiling mixture. In industrial design and thermodynamics, it describes processes, phase equilibrium phenomena, or separation methods (such as azeotropic distillation) utilized to manipulate or purify complex liquid systems whose components boil without changing their structural composition.
• Azeotropy — 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.
