Solubility and equilibrium data for phenol-aqueous sodium salicylate (54 per cent)-a-methyl naphthalene system at 34) C. are reported. The system exhibits two types of curves the ordinary bite type curve and a small convex loop with a solid and liquid phase typical of systems containing water and an inorganic salt. The tie-line data fit with most of the empirical relationships reported in literature. The plait point for the system is at 360 per cent phenol concentration. AND The use of aqueous saturated sodium salicylate for the extraction of tar acids from a low-temperature tar fraction is discussed. Solubility and equilibrium data for the system neutral oil-tar acids-aqueous sodium salicylate when plotted on a ternary diagram showed two types of curves: an ordinary bite type and another a loop containing solid and liquid phases. The tie-line data agree with most of the empirical relationships reported in the literature. The plait point for the system had a tar acid concentration of 47%. The results have been compared with the earlier data for the system: phenol-a-methylnaphthalene-aqueous sodium salicylate
