Infinite Dilution Activity Coefficients in Mono-, Di-, and Tripalmitin and Palmitic Acid

Abstract

Infinite dilution activity coefficients of several organic solutes in mono-, di-, and tripalmitin and in palmitic acid were measured by gas chromatography, at temperatures between 353 K and 373 K. The solutes include hydrocarbons, chlorinated hydrocarbons, and alcohols. The UNIFAC group contribution model and Flory's combinatorial model, with the addition of a regular solution residual term, were used to correlate the experimental data.
