摘要
探讨了不同馏分石油酸钠的水溶性规律，结果表明，石油酸钠的数均相对分子质量（Ｍｒ）及水相中电解质的浓度是影响其水溶性的主要因素：升高温度有利于石油酸钠在水中的溶解；但在一定的条件下，石油酸钠加入量少，反而要求较高的溶解温度；Ｍｒ小的石油酸钠对Ｍｒ较大的石油酸钠具有明显的增溶作用；一定量的中性油也会增加石油酸钠在水中的溶解度。
The solubility and solubilization properties of sodium naphthenates were examined.The solubility of sodium naphthenates in water decreased drastically with the increase of the Mr of the naththenates and the concentrations of electrolytes in water.Rise of temperature favors the solubility of sodium naphthenates in water.When content of sodium naphthenates is comparatively low,higher temperature is needed to dissolve the naphthenates completely.Addition of sodium naphthenates with low Mr can increase the water solubility of those with higher Mr remarkably.Hydrocarbon can also help dissolve sodium naphthenates in water.
