Ethyl alcohol volatility
WebAs of Feb 2012, there are four volatility classes defined for ethanol fuel blends. These classes define a volatility range, and the specification is as follows: Class 1 (RVP = 5.5-8.5) Class 2 (RVP = 7.0-9.5) Class 3 (RVP = 8.5-12.0) Class 4 (RVP = 9.5-15.0) The class requirements change throughout the year as the average temperature changes.

WebEthanol is a longer molecule, and the oxygen atom brings with it an extra 8 electrons. Both of these increase the size of the van der Waals dispersion forces, and subsequently the boiling point. A more accurate measurement of the effect of the hydrogen bonding on boiling point would be a comparison of ethanol with propane rather than ethane. WebRelative volatility of ethanol (1) to water (2) at 101.3 kPa at different IL concentrations: , x 3 = 0; •, x 3 = 0.05; , x 3 = 0.10; , x 3 = 0.15; solid lines, correlated using the NRTL model.

Ethanol boils at … An important factor influencing a substance's volatility is the strength of the interactions between its molecules. Attractive forces between molecules are what holds materials together, and materials with stronger intermolecular forces, such as most solids, are typically not very volatile.
