用气相色谱法对火药中异丙醇、乙酸乙酯和苯的含量进行测定。样品用甲醇提取，采用氢火焰检测器检测，检测器温度200℃，柱箱温度145℃，气化室温度190℃，载气为氮气，流速50 mL/min,外标法定量。该方法对异丙醇、乙酸乙酯和苯的最低检测浓度为0.5,0.3,0.6μg/mL；在5～100μg/mL浓度范围内均呈良好的线性关系，线性系数r＞0.990；方法回收率在94.8%～96.5%之间，相对标准偏差（n=6）在2.5%～3.6%之间。符合火药质量检测的要求，方法可用于火药中异丙醇、乙酸乙酯和苯含量的检测。

Contents of isopropanol,ethyl acetate and benzene in propellant were determined by gas chromatography. The samples were extracted by methyl alcohol, detected by FID detector; respective temperatures of detector, column oven, vaporizer were 200℃, 145℃, 190℃. The carrier gas was nitrogen and its flow rate was 50 mL/min, the analytes were quantified with an external standard method. And the detection limits of isopropanol,ethyl acetate and benzene were 0.5 μg/mL ,0.3 μg/mL and 0.6 μg/mL,respectively. All of the target compounds exhibited good linearity (r>0.990) in the concentration range of 5~100 μg/mL. Values of recovery and RSD’s(n=6) found were in ranges of 94.8%~96.5% and 2.5%~3.6%,repectively, which accorded with the requirements of the quality of propellant determination. So the method can be used for detection of isopropanol,ethyl acetate and benzene in propellant.
