摘　　要：本文介绍了以乙酸酐为溶剂，高氯酸的冰乙酸标准溶液为滴定剂，用玻璃电极-改良的甘汞电极进行非水滴定测定六甲基磷酰三胺百分含量的方法。此法简便快速，平均回收率为100．05％，标准偏差为0．22，可用于指导工业生产。A method to determine the hexamethl phosphoric triamide content has been described in the paper. Using a glass electrode and the sleeve-type calomel electrode,and taking the acetic anhydride as the solvent, standard perchloric acid solution in glacial acetic acid as the titrant,the method is convenient and rapid. The average recovery ratio is 100. 05 % and the standard deviation is 0. 22. The method can be utilized in the industrial production.
