FERREIRA, O.  and  FOCO, G. M.. Infinite dilution activity coefficients of solvents in fatty oil derivatives. Lat. Am. appl. res. [online]. 2003, vol.33, n.3, pp.257-260. ISSN 0327-0793.

Inverse gas-liquid chromatography has been applied to measure infinite dilution activity coefficients (g¥ ) of different solutes in low and high molecular weight triacylglycerides (TAGs) and in mixtures of carboxylic acids with TAGs. The g¥ data obtained were used to determine binary interaction and size related parameters for the GCA-EOS group contribution with association equation of sate.

Keywords : Activity Coefficients; Infinite Dilution; Carboxylic Acids; Triglycerides; Parameters Determinations; Binary Interaction.
