气相色谱法测定火药中定剂含量研究

Study on Determination of Propylthiouracil in the Propellant by GC

建立了一种新的气相色谱测定火药中定剂的方法。选择特定的外标标准物作外标可以消除火药试验提取时存在的浸取不完全性缺陷,并用化学法验证了它的正确性。该法简单、快速、精密度和准确度高、安全无毒,符合火药质量检测的要求,方法可用于火药中中定剂含量的检测。

A new analytical method was established to determine propylthiouracil in the propellant.The specific external standard was used to eliminate the defect that the propylthiouracil was incompletely extracted. And the method’s validity was verified by chemical method. The results show that the method is simple and rapid in operation, has high precision and accuracy, and can be used for detection of propylthiouracil in propellant.
