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.
The boiling points of alcohols are much higher than those of alkanes with similar molecular weights. For example, ethanol, with a molecular weight (MW) of 46, has a boiling point of 78 °C (173 °F), whereas propane.
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. Implications of Different Boiling Points.

Ethanol is a liquid at standard conditions. However, at low temperature and/or very high pressures it becomes a solid. The phase diagram for ethanol shows the phase behavior with changes in temperature and pressure. The curve between the critical point and the triple point shows the ethanol boiling point with changes in pressure.
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.
