2,3-dimethyl-2,3-dinitrobutane (DMNB) has been internationally accepted as an additive for the purpose of marking, as it has desired vapour pressure for reliable detection. It is reported to be compatible with known explosive formulations and has a good shelf life. Explosive compositions with DMNB as marking agent can be detected in the temperature range –20°C to + 50°C. This paper describes modelling for quantifying activation energy for depletion of DMNB in the marked explosives, period for definite detection of the marked explosives and optimum initial concentration needed for the detection of DMNB content in the marked plastic explosives.
