摘　　要：用气相色谱法对火药中二苯胺、间苯二酚含量进行测定。样品用乙醚提取,采用热导检测器检测。方法回收率在94.4%~96.5%之间,相对标准偏差（n=6）在2.4%~3.5%之间。符合火药质量检测的要求,方法可用于火药中二苯胺、间苯二酚含量的检测。The contents of diphenylamine and m-dihydroxybenzene in propellant were determined by gas chromatography. The samples were extracted by ether, detected by TCD detector. Values of recovery and RSD ’s（n=6）found were in ranges of 94.4%~96.5% and 2.4%~3.5% repectively, which accorded with the requirements of the quality of propellant determination, and it can be used for the detection of diphenylamine and m-dihydroxy-benzene in propellant.
