Determination of bis(2,2-dinitropropyl) acetal/formal in PBX 9501
PBX 9501 is an explosive which will be utilized in future programs. As such, much interest has been expressed in the chemical assay of this material. The purpose of the study was to develop an accurate, precise determination of the two major components in the NP. In this technique a sample of PBX 9501 is extracted with methylethylketone (MEK). The residue from this extract is then leached with hexane, evaporated to dryness and then taken up in MEK. An aliquot is injected into an LC system using a Partisil 5 column and an 85-15 Hexane/MEK carrier. The separated species are detected with an RI indicator and compared with a calibration curve. The method is unbiased and relative precisions of analysis are 2.5% and 3% for BDNPF and BDNPA, respectively.
