测定了甲苯在蒸馏水和各种无机盐溶液中的溶解度。Setschenow常数（KS）的值，用于量化甲苯溶解度与盐浓度的关系，已经确定了每种盐的值。盐溶液的KSare值与水的活度比较。本研究的数据与先前的数据一致，表明盐对甲苯溶解度的影响是非加性的。这对比了无机盐对非极性有机化合物（如苯和萘）溶解度的添加剂行为，在文献中报道。微极性甲苯与溶液中离子之间的特殊相互作用可能是盐对甲苯溶解度的非加性影响的一种解释。
The solubility of toluene has been measured in distilled water, and in various inorganic salt solutions. Values of the Setschenow constant, KS, which quantify toluene solubility versus salt concentration, have been determined for each salt. Values of KSare compared to the activity of water for the salt solutions. Data from this study, consistent with earlier data, suggests that the effects of salts upon toluene solubility are non-additive. This contrasts the additive behavior of inorganic salts upon the solubility of nonpolar organic compounds, such as benzene and naphthalene, reported in the literature. Specific interaction between slightly polar toluene and ions in solution is suggested as a possible explanation for the non-additive effect of salts on the solubility of toluene.
