测定了纯5-磺基水杨酸及其与对氨基苯甲酸等摩尔混合物在超临界二氧化碳中的溶解度，温度为308~328 K，压力范围为8.0~21.0 Mpa。研究了温度和压力对溶解度的影响，并研究了混合溶质之间的相互作用。用该方程对5-磺基水杨酸和对氨基苯甲酸的二元和三元溶解度数据进行了关联，结果令人满意。
The solubilities of pure 5-sulfosalicylic acid and its equal-molar mixture with p-aminobenzoic acid in supercritical carbon dioxide were measured at (308 to 328) K and over the pressure range from (8.0 to 21.0) MPa. The effect of temperatures and pressures on the solubility was investigated, and the interaction of the mixed solutes was also studied in this work. The binary and ternary solubility data of 5-sulfosalicylic acid and p-aminobenzoic acid were correlated by the Chrastil equation with satisfactory agreement.
