Infinite dilution volatilities of polar solutes in hydrocarbons

Authors


Abstract

Infinite dilution volatility data have been correlated for alcohols, esters, aldehydes, ketones, and sulfur containing hydrocarbon solutes in aliphatic hydrocarbon solvents over a wide temperature range using a temperature dependent energy parameter for the pure solute.

When a polar solute molecule is surrounded entirely by nonpolar molecules, polar molecular interactions such as hydrogen bonding do not play an important role. Therefore, a single, pure solute parameter is sufficient for correlation.

Calculated heats of solution at infinite dilution agree well with published calorimetric data.
