溴化法测定硝基胍发射药中定剂含量实验

Determination of Centralite of Nitroguanidine Propellant by Bromination

采用溴化法测定硝基胍发射药中定剂含量,摸索适宜的提取条件:采用体积比为2:1的正戊烷-二氯甲烷作为提取液,提取温度为60℃,提取时间为4 h。

The bromination method was adopted to nitroguanidine propellant for fixed agent in the determination of groping suitable extraction conditions: using 2 ∶ 1 volume of n-pentane-dichloromethane as the extract, the extraction temperature is 60 ℃, and the extraction time is 4 h.
