Activity coefficient at infinite dilution measurements for organic solutes (polar and non-polar) in fatty compounds: Saturated fatty acids

► Limiting activity coefficient for 21 solutes in four saturated fatty acids was measured. ► Thermodynamic functions were derived for capric, lauric, myristic, and palmitic acids. ► Different trends for polar and non-polar solutes could be identified. ► The results allow a more accurate description of the real behavior of fatty systems.
