摘　　要：提出了采用反相高效液相色谱法测定含RDX的叠氮硝胺发射药中RDX、硝化甘油(NG)、1,5-二叠氮基-3-硝基氮杂戊烷(DIANP)和中定剂(C2) 4种组分含量的新方法;试样用丙酮溶剂溶解后进行色谱分离,采用Agilent Cl8色谱柱(5μm,4. 6 mm×150 mm),以乙腈和水(体积比为65∶35)为流动相,在波长210 nm处进行4种组分含量的测定。结果表明,在优化的色谱条件下,NG在质量浓度0. 02～1. 38 g/L,RDX在质量浓度0. 02～1. 11 g/L,DIANP在质量浓度0. 02～0. 98 g/L,C2在质量浓度0. 002～0. 12 g/L时,含量分别与其峰面积呈线性关系; 4种化合物的加标回收率在98. 4%～100. 6%,相对标准偏差RSD在0. 53%～1. 20%。表明该方法准确可靠,可用于含RDX的叠氮硝胺发射药组分含量的测定。A new method for the determination of four components,including hexogen(RDX),nitroglycerine(NG),1,5-diazido-3-nitraapentane(DIANP)and methyl centralite(C2)in azidonitramine gun propellant containing RDX by reversed phase-high performance liquid chromatography(RP-HPLC)was proposed.The sample after dissolution was chromatographically separated and the contents of the four components were determined at wavelength of210nm using Agilent Cl8chromatographic column(5μm,4.6mm×150mm),and acetonitrile and water with volume ratio of65∶35as mobile phase.The results show that under the optimized chromatographic conditions,when the mass concentration of NG,RDX,DIANP and C2is in ranges of0.02-1.38g/L,0.02-1.11g/L,0.02-0.98g/L,0.002-0.12g/L,respectively,their mass concentration has a linear relation with peak area.The recoveries of standard addition for the four compounds are between98.4%and100.60%,and their relative standard deviations(RSD)are between0.53%and1.20%.The results show that this method is accurate and reliable,and can be used to determine the content of azidonitramine gun propellant containing RDX.
