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. [87]

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
A study that did not prevent respiratory uptake found that applying 200 mL of hand disinfectant containing 95% w/w ethanol (150 g ethanol total) over the course of 80 minutes in a 3-minutes-on 5-minutes-off pattern resulted in the median BAC among volunteers peaking 30 minutes after the last application at 17.5 mg/L (0.00175%).
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.
