【摘要】 采用混合溶剂电位滴定法测定壬基酚聚氧乙烯醚磷酸酯中单酯、双酯、磷酸的含量．考察了溶剂种类及其配比，滴定剂溶剂及滴定剂浓度的影响；确定了最佳分析条件：溶剂为95％乙醇／甲苯为1：1；滴定剂为0．2000mol／L标准氢氧化钠乙醇溶液．该方法操作简单、计算方便、可广泛应用于工业生产中．更多还原

【Abstract】 The paper shows the content 0f m0no - ester, di - ester and phosphoric acid in phosphateP0lyoxyethylene nonylphenol by mixed - solvents POtentiontric titration. The sort and ratio of the solvents,the solvents and concentrati0ns 0f the titrant were studided. An optimum analytic c0ndition is determined.The alcohol(95 % )/toluene was 1: l; the titrant was 0. 20OO mol. I, - l sodium hydro - xide alcoh0l solution.This method is not only simple in operation but also easy in calculation. lt widely app1ies to industrial pro-duct ion.更多还原
