IDENTIFICATION Product Name: n-Propyl alcohol CAS#: 71-23-8 (1% soln/water): 7 [Neutral.] Boiling Point: 97.22°C (207°F) Melting Point: -126.2°C (-195.2°F) Critical Temperature: Not available. Specific Gravity: 0.8053 (Water = 1) Vapor Pressure: 14.9 mm of Hg (@ 20°C) Propionic acid (10 mM) inhibited hepatocyte oxidation of 1-(14)C-pyruvate (10 mM) by 60%. This inhibition was not the result of substrate competition, as butyric acid had minimal effects on pyruvate oxidation. Propionic acid also inhibited oxidation of 1-(14)C palmitic acid (0.8 mM) by hepatocytes isolated from fed rats. These results Therefore, there are stronger intermolecular forces between 1-propanol molecules than between 2-propanol molecules. Higher intermolecular forces -> more energy needed to pull molecules apart from each other to convert from a liquid state to gaseous, so a higher boiling point. 5. 25M subscribers in the askscience community. Here is a look at the boiling point of different types of alcohol. 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. The boiling point of this mixture is 78.2°C, compared with the boiling point of pure ethanol at 78.5°C, and water at 100°C. You might think that this 0.3°C doesn't matter much, but it has huge implications for the separation of ethanol / water mixtures. The next diagram shows the boiling point / composition curve for ethanol / water mixtures.
