硝基胍发射药化学安定性的气相色谱测定方法

Gas Chromatographic Method for Estimating Chemical Stability of Nitroquanidine Propellant

介绍硝基胍发射药化学安定性色谱试验方法：将定量火药试样在定容下加热一定时间后，用归一化计算的气相色谱法对热分解气体CO2和N2O含量进行测定。方法对库存火药化学安定性的检测有很好的适用性。

This paper describes a GC analytical method for nitroquanidine propellant instead of the tranditional methylviolet method' Operating conditions were as follows: TDX-01 packed column, 150-200 mesh, 800 min×3 mm i. d., at 150-170℃ with TCD. Released gases, CO2 and N2O contents in a sealed vessel packed with nitroquanidine were calculated according to the normalization of corrected peak areas of air, CO2 and N2O. Thus, the change in the chemical stability of nitroquanidine during the period of storage and thermal aging could be observed.
