Theoretical boiling point of ethanol
WebbThe boiling point of ethanol at one atmosphere is 78.5°C. The boiling point of the ethanol : water azeotrope is 78.2°C. The implications for separation by distillation are obvious. As the azeotrope boils at a lower temperature than either pure ethanol or pure water, it is impossible to distil pure ethanol. Webb13 sep. 2024 · According to some aspects, the perfluorocarbon has a boiling point approximately no greater than the boiling point of perfluoropropane (about -37 °C). According to some aspects, the perfluorocarbon has a boiling point no greater than about -5, -10, -15, -20, -25, -30, -35, or -40 °C.
