The minimum-pressure azeotrope has an ethanol fraction of 100% [86] and a boiling point of 306 K (33 °C), [85] corresponding to a pressure of roughly 70 torr (9.333 kPa). [87] Below this pressure, there is no azeotrope, and it is possible to distill absolute ethanol from an ethanol-water mixture.

The liquid–liquid critical point of a solution, which occurs at the critical solution temperature, occurs at the limit of the two-phase region of the phase diagram. In other words, it is the point at which an infinitesimal change in some thermodynamic variable (such as temperature or pressure) leads to separation of the mixture into two ...
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 specific gravity of the mixture.
