作者测定在25°下正己酸在五种脂肪酸钠(甲,乙,丙,丁,戊)溶液中的溶度。这些盐对正己酸都起盐溶作用。盐溶的原因是正己酸对这些盐起部分的排代反应而产生新的酸。但是新的酸可能分布在盐溶液相和正己酸间,使实验的溶度小于计算值。

The solubilities of caproic acid in aqueous solutions of sodium salts of fivefatty acids (C1 to C5) have been measured at 25℃. All these salts increase thesolubilities of caproic acid. The reason for salting-in is due to partial displacement of the salt by thecaproic acid producing a new acid. But the new acid may distribute itself betweenthe aqueous salt, solution phase and the caproic acid phase thus rendering the actualsolubilities less than the calculated values.
