Abstract

The surface areas for 73 aliphatic hydrocarbons and alcohols, for which solubility and boiling point data are available, were calculated. The solubility of the alcohols and hydrocarbons can be quantitatively related to a combination of the hydrocarbon and hydroxyl surface areas of the molecules. The boiling points of the alcohols also correlated well with these two parameters. Isomeric alcohols, having a lower hydrocarbon surface area and/or a lower hydroxyl group surface area, are more soluble in water. The correlations show that branching, cyclization, and positional isomerism can be accounted for without introducing additional terms.
