Azeotrope

A solution that does not change composition when distilled. For example, if a 95% (w/w) ethanol solution in water is boiled, the vapour produced also is 95% ethanol- and it is not possible to obtain higher percentages of ethanol by distillation.

azeotrope

Azeotrope is a mixture of two liquids that boils at constant composition, i.e. the composition of the vapour is the same as that of the liquid. Azeotropes occur because of deviations in Raoult's law leading to a maximum or minimum in the boiling point - composition diagram. The composition of an azeotrope depends on the pressure.

Azeotrope

A mixture of two or more compounds which has a constant boiling point. The composition of the vapour above the azeotropic mixture has the same relative concentrations of compounds as does the boiling liquid. Azeotropic mixtures cannot be separated by fractional distillation

azeotrope

A ‘constant boiling mixture` of two or more solvents, whose vapour has the same composition as the liquid, so that the formulation cannot be altered by distillation. Constant boiling mixtures usually have a minimum boiling point, lower than that of either of its constituents. Often azeotropes used for cleaning combine polar and non-polar sol...

Azeotrope

[data] This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the ...

Azeotrope

An azeotrope (p {respell|ə|ZEE|ə-trohp} or p {respell|AY|zee-ə-trohp}) is a mixture of two or more liquids whose proportions cannot be altered by simple distillation. This happens because, when an azeotrope is boiled, the vapor has the same proportions of constituents as the unboiled mixture. Because their composition is unchanged by distillati...
