摘　　要：用核磁共振波谱技术对纯度标准物质黑索金(RDX)中残余溶剂进行了定性分析,确定了RDX标准物质中含有残余溶剂丙酮。同时采用核磁共振内标法和免称法,分别对丙酮含量进行了定量分析。平行测定12次,内标法测定结果和测定相对标准偏差分别为0.0258%和2.27%;免称法测定结果和测定相对标准偏差分别为0.0248%和2.26%。Qualitative analysis of remnant solvents in reference material of cyclotrimethyl-enetrinitramine（RDX）was identified as acetone by NMR.The content of acetone was determined by the internal reference method of NMR as 0.0258% with relative standard deviation（RSD）of 2.27%（n=12）.The content was also determinbed as 0.0248% by the non-weighing method（n=12）with the RSD of 2.26% respectively.
