#azeotropy

• 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.
• Azeotropism — A fundamental property of certain liquid chemical mixtures or copolymerization systems to behave as an unchanging whole during phase transitions or synthesis reactions. In polymer chemistry, azeotropism describes the structural state in which the composition of the monomer mixture remains constant throughout the reaction, giving rise to a copolymer with a perfectly uniform molecular distribution and refined mechanical properties.
