摘要
采用电位滴定法测定了十二烷基磷酸酯中单酯、双酯、磷酸的含量。考察了溶剂种类及配比 ,滴定剂溶剂及滴定剂浓度、10 % Ca Cl2 及饱和 Na Cl用量的影响。确定了最佳分析条件。该法操作简单、计算方便、可应用于工业生产中。
The monoester,disester and phosphoric acid in dodecyl phosphate were determined by potentiometric titration.The influence factors,such as selection,ratio of solvent,solvent and concentration of titrant,the addition of 10% CaCl 2 and saturate NaCl were studied.The best analytical condition was obtained.
