摘要
研究表明，石油酸钠平均相对分子质量越大，对馏分油的增溶能力越强；水相中石油酸钠浓度越大，对馏分油的增溶能力越强；水相中无机电解质浓度越大，石油酸钠对馏分油的增溶能力越强。在馏分油的碱洗脱酸过程中，必然会发生石油酸钠对馏分油的增溶作用。
Sodium naphthenate in aqueous solution can solubilize oil fractions durmg caustic treatment.The solubilization capacity increases with the increase of relative molecular mass of sodium naphthenate or its concentration.The increase of concentration of inorganic electrolyte in aqueous phase can also markedly raise the solubilization capacity of sodium naphthenates for oil.The solubilization capacity is almost not affected by temperature in the range of 60～90℃.
