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.

Experimental data on infinite dilution activity coefficients of hydrocarbons, chlorinated hydrocarbons, alcohols, ethers, and ketones in triacetin and tributyl phosphate are presented. The measurements were made by inverse gas chromatography. A temperature range between 323 K and 353 K was covered. The solubility parameters of tributyl phosphate and triacetin were determined from the experimental data.
