Boiling Point: 207 °F at 760 mm Hg: Melting Point-195.2 °F : Appearance : Colourless liquid: Odour: Similar to ethanol: tertiary alcohol, and phenol are the four known alcohols. 1-propanol, 2-propanol, 2-methyl-2-butanol, and para-chlorophenol are the four possible unknown alcohols. Uses of Propanol. liquid is the temperature at which the vapor pressure of a liquid equals atmospheric pressure (1 atm). The boiling point of a liquid is a measure of its volatility. 1-propanol : 97. 3-Ethylpentane : 93.5. 2,2,4-Trimethylpentane : 99.2. Acetone : 57 . 56- Methanol : 65 . Ethanol : 78-79 .

To be used in place of 1,2-propanediol (as specified in 21 CFR 184.1666(c)) at levels not to exceed current good manufacturing practice; maximum levels of 5 percent for alcoholic beverages, 24 percent for confections and frostings, 2.5 percent for frozen dairy products, 97 percent for seasonings and flavorings, 5 percent for nuts and nut products and 2 percent for all other food categories There are two isomers of propanol.. 1-Propanol, n-propanol, or propan-1-ol : CH 3 CH 2 CH 2 OH, the most common meaning; 2-Propanol, Isopropyl alcohol, isopropanol, or propan-2-ol : (CH 3) 2 CHOH See also. Propanal (propionaldehyde) differs in spelling from propanol by a single letter and is a different compound.; Propranolol is a drug used for reducing blood pressure and hand tremors. In summary, the boiling point of 2-propanol is lower than 1-propanol due to its decreased surface area leading to weaker dispersion forces and a lower net permanent dipole moment towards the oxygen atom. This results in easier separation of molecules and a lower boiling point. 7Dt2t.
