| 摘 要： | 研究了3-二乙氨基苯酚含量的非水滴定法测定条件,建立了以醋酸-醋酐为溶剂,高氯酸(0.1mol/L)标准滴定溶液作滴定剂,电位法指示终点的快速、准确、精密度高的测定方法。考察了凝固点和含量两个变量之间的相关系数为r=0.959,r>r0.01为显著性相关。

| Abstract: | The conditions of nonaqueous titrimetry to determine the content of 3-Biethymine Phenol was stndied.,a speedy, nicety and high precision method was established using vinegar acid-vinegar anhydride as solvent,HClO_ 4 (0.1mol/L) standard solution as titration reagent,and with PotentiometricTitration indicating the terminal.The eorrelation modulus beiween the fieezing pionl and the content was r=0.959,it's a marked correlation when r_ 0.01 . |
