Example types with azeotrope
The same corpus examples are grouped by length and sentence type, making it easier to see the contexts in which the word appears:
This type of azeotrope is called heterogeneous azeotrope. (8 words)
There are two types of azeotropes: minimum boiling azeotrope and maximum boiling azeotrope. (13 words)
An example is acetic acid and water, which do not form an azeotrope. (13 words)
Distillation of mixtures If two solvents can form a positive azeotrope, then distillation of any mixture of those constituents will result in the distillate being closer in composition to the azeotrope than the starting mixture. (35 words)
CRC Handbook of Chemistry and Physics, 44th ed., p. 2181 Just enough cyclohexane is added to the water/ethanol azeotrope to engage all of the water into the ternary azeotrope. (30 words)
At an azeotrope, the solution contains the given component in the same proportion as the vapor, so that evaporation does not change the purity, and distillation does not effect separation. (30 words)

Distillation of mixtures If two solvents can form a positive azeotrope, then distillation of any mixture of those constituents will result in the distillate being closer in composition to the azeotrope than the starting mixture.
Each pair of these constituents forms a binary azeotrope, but chloroform/methanol and acetone/methanol both form positive azeotropes while chloroform/acetone forms a negative azeotrope.
If the azeotropic composition is outside the miscibility gap or the constituents of the mixture are completely miscible, the type of azeotrope is called a homogeneous azeotrope.
Note that starting to the right of the azeotrope point results in the same stepwise process closing in on the azeotrope point from the other direction.
There are two types of azeotropes: minimum boiling azeotrope and maximum boiling azeotrope.
This type of azeotrope is called heterogeneous azeotrope.
A hypothetical azeotrope of constituents X and Y is shown in the diagram to the right.
An example is acetic acid and water, which do not form an azeotrope.
A solution that shows greater positive deviation from Raoult's law forms a minimum boiling azeotrope at a specific composition.
At an azeotrope, the solution contains the given component in the same proportion as the vapor, so that evaporation does not change the purity, and distillation does not effect separation.
A well-known example of a positive azeotrope is 95.63% ethanol and 4.37% water (by weight).
Because the azeotrope's vapor pressure is higher than predicted by Raoult's law, it boils at a temperature below that of either pure component.
By adding ethyl acetate as an entrainer, it is possible to distill away the azeotrope and leave nearly pure acetic acid as the residue.
Dilute nitric acid may be concentrated by distillation up to 68% acid, which is a maximum boiling azeotrope containing 32% water.
Extractive distillation Extractive distillation is similar to azeotropic distillation, except in this case the entrainer is less volatile than any of the azeotrope's constituents.
For example, ethyl alcohol and water form an azeotrope of 95.6% at 78.1 °C.
For example, the azeotrope of 20% acetone with 80% chloroform can be broken by adding water and distilling the result.
Hydrogen chloride boils at −84 °C and water at 100 °C, but the azeotrope boils at 110 °C, which is higher than either of its constituents.
If the deviation is large, then the vapor pressure curve shows a maximum at a particular composition and form a positive azeotrope.
