Azeotropes can form only when a mixture deviates from Raoult's law, the equality of compositions in liquid phase and vapor phases, in vapour-liquid equilibrium and … See more An azeotrope or a constant heating point mixture is a mixture of two or more liquids whose proportions cannot be altered or changed by simple distillation. This happens because when an azeotrope is boiled, the vapour … See more If the two solvents can form a negative azeotrope, then distillation of any mixture of those constituents will result in the residue being closer to the composition at the azeotrope than the original mixture. For example, if a hydrochloric acid solution contains less than … See more • Azeotrope tables • Azeotropic distillation • Bancroft point • Batch distillation • Ebulliometer See more The term azeotrope is derived from the Greek words ζέειν (boil) and τρόπος (turning) with the prefix α- (no) to give the overall meaning, "no change on boiling". The term was coined in 1911 by English chemist John Wade and Richard William Merriman. See more Positive and negative azeotropes Each azeotrope has a characteristic boiling point. The boiling point of an azeotrope is either less than the boiling point temperatures of any of its constituents (a positive azeotrope), or greater than the boiling point of any … See more The rules for positive and negative azeotropes apply to all the examples discussed so far, but there are some examples that don't fit into the categories of positive or negative azeotropes.

Azeotropic distillation - Wikipedia

WebAZEOTROPIC DATA FOR BINARY MIXTURES Liquid mixtures having an extremum (maximum or minimum) vapor pressure at constant temperature, as a function of composition, are called azeotropic mixtures, or simply azeotropes. Mixtures that do not show a maximum or minimum are called zeotropic. WebIPA is soluble in water and it forms azeotrope with water at temperature 80.3-80.4 0C. IPA and water forms a homogeneous minimum boiling azeotrope, at 68.1-67.5 mole% (87.4-87.7 mass %) under atmospheric conditions [1]. ….
