Jun 13, 2024 · For example, ethanol, with a molecular weight (MW) of 46, has a boiling point of 78 °C (173 °F), whereas propane (MW 44) has a boiling point of −42 °C (−44 °F). Such a large difference in boiling points indicates that molecules of ethanol are attracted to one another much more strongly than are propane molecules.
Ethanol is considered a universal solvent, as its molecular structure allows for the dissolving of both polar, hydrophilic and nonpolar, hydrophobic compounds. As ethanol also has a low boiling point, it is easy to remove from a solution that has been used to dissolve other compounds, making it a popular extracting agent for botanical oils.
Nov 28, 2022 · The boiling point of ethanol or grain alcohol (C 2 H 5 OH) at atmospheric pressure (14.7 psia, 1 bar absolute) is 173.1 F (78.37 C). Methanol (methyl alcohol, wood alcohol): 66°C or 151°F. Isopropyl Alcohol (isopropanol): 80.3°C or 177°F. Read More. Freezing Points of Various Alcohols Unveiled. By Anne Marie Helmenstine, Ph.D.

The curve between the critical point and the triple point shows the ethanol boiling point with changes in pressure. It also shows the saturation pressure with changes in temperature. At the critical point there is no change of state when pressure is increased or if heat is added.

The boiling point of an alcohol is always significantly higher than that of the analogous alkane. The boiling points of the alcohols increase as the number of carbon atoms increases. The patterns in boiling point reflect the patterns in intermolecular attractions.
Jun 20, 2024 · Pure ethanol is a colourless flammable liquid (boiling point 78.5 °C [173.3 °F]) with an agreeable ethereal odour and a burning taste. Ethanol is toxic, affecting the central nervous system.
Boiling Point: 72.6±3.0 °C at 760 mmHg Vapour Pressure: 82.8±0.2 mmHg at 25°C Enthalpy of Vaporization: 38.6±0.0 kJ/mol Flash Point: 8.9±0.0 °C Index of Refraction:
Mar 19, 2024 · The boiling point of pure ethanol at standard atmospheric pressure (1 atm or 101.3 kPa) is 78.37°C (172.87°F). This value is widely accepted and used in various applications, such as in the design and operation of distillation columns, temperature sensors, and other equipment that involves the handling or processing of ethanol.
