Abstract : This paper gives the results of a study on estimation of shelf life of 2,3-dimethyl2,3-dinitrobutane (DMNB)-tagged RDX and PETN explosives by monitoring DMNB depletion by high performance liquid chromatography and simultaneously recording the detectability of the tagged explosive composition using explosive vapour detector Model-97 HS. DMNB was incorporated in the explosive using methanol as solvent for DMNB and the explosive compositions were stored at 35,55 and 75 °C over a long period. Methods developed for preparing the homogeneously tagged composition with DMNB at 0.5 per cent level and for the analysis ofDMNB for ensuring homogeneity of DMNB in the composition are described. The results show no change in compatibility and sensitivity on the incorporation of DMNB in the explosive. Estimation of shelf life of DMNB in the explosive was done for a period of storage of 202-304 days at different temperatures.
