#boiling point

• Azeotrope — A liquid mixture consisting of two or more chemical components that boils at a constant and fixed temperature, maintaining its identical structural composition in both the liquid and vapor phases. Because the generated vapors have exactly the same proportions of substances as the liquid from which they originate, an azeotrope cannot be separated or purified by simple fractional distillation, behaving thermodynamically like a single pure compound and requiring special separation methods, such as extractive azeotropic distillation.
• 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.
