The minimum-pressure azeotrope has an ethanol fraction of 100% [85] and a boiling point of 306 K (33 °C), [84] corresponding to a pressure of roughly 70 torr (9.333 kPa). [86] Below this pressure, there is no azeotrope, and it is possible to distill absolute ethanol from an ethanol-water mixture.

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.
The boiling point of the alcohol ethanol is 78.29 °C, compared to 69 °C for the hydrocarbon hexane, and 34.6 °C for diethyl ether. Occurrence in nature
Water boiling at 99.3 °C (210.8 °F) at 215 m (705 ft) elevation. The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid [1] [2] and the liquid changes into a vapor.
