Experimental data have been obtained over the temperature range of (40 to 50) °C. In this work, activity coefficients at infinite dilution for different kinds of systems have been considered: one component solute + water and multicomponent solute + water. No significant differences were observed between activity coefficients obtained in these two kinds of systems. Additionally the effect of salt concentration at 40 °C has been studied by varying the salt concentration from (0 to 1.71) mol·kg−1. Experimental data were fitted as a function of salt concentration by using the Setschenow equation, obtaining the salting-out coefficient. eng info:eu-repo/semantics/openAccess aroma compounds activity coefficients at infinite dilution salt effect temperature effect Activity coefficients at infinite dilution of volatile compounds in water: effect of temperature and salt concentration info:eu-repo/semantics/article
