dc.description.resumoThe activity coefficients at infinite dilution , c113 (the subscript 1 and 3 correspond to solute and solvent, respectively), for 21 solutes, including alkane, cycloalkane, alkene, aromatic compounds, alcohol, ester, ketone, and halogenated hydrocarbons, in four solvents, that are the saturated fatty acids: capric (decanoic) acid, lauric (dodecanoic) acid, myristic (tetradecanoic) acid, and palmitic (hexadecanoic) acid, were determined by gas–liquid chromatography at temperatures from 314.10 K to 358.33 K. Comparison with previously published for selected solutes in palmitic (hexadecanoic) acid were also performed. The values of the partial molar excess Gibbs free energy, DG113, enthalpy, DH113, and entropy, DS113, at infinite dilution were calculated from experimental c113 values obtained over the temperature range. Results obtained in this work allow a more accurate description of the real behavior of fatty systemspt_BR
