摘要
以二甲基甲酰胺作溶剂,采用二正丁胺滴定法测定聚氨酯合成革预聚体中的异氰酸酯基含量,发现用二甲基甲酰胺—二正丁胺法测定值与传统方法相比准确度相差不大,但精确度较高,本方法精确、简便,有效降低了实验成本。
The dimethylformamide-dibutylamine method for testing isocyanate group content in polyurethane prepolymer is developed.The results indicated that the new test method was similar to the traditional method in the accuracy,but had the higher precision.This new method is accurate,simple and effective,and reduces the test cost.
