The explosive, 2,6-bis(picrylamino)-3,5-dinitropyridine is prepared by
(a) reacting, in a polar protic solvent, 2,6 diaminopyridine with at least one compound having the general formula
wherein:
X is a halogen or an alkoxy group containing 1 to 4 carbons, provided however that when X is a halogen, at least one base material selected from alkaline earth metal carbonates and alkali metal bicarbonates, is present in an amount of at least one molar equivalent to said compound,
(b) filtering the reaction product of step (a); and
(c) nitrating the filtered reaction product of step (b) with at least 90 percent nitric acid at a temperature in the range of about 32°F (0°C) to about 85°F (30°C).

The present invention relates to methods for producing non-detonable and non-explosive parent-odor scent simulants of both detonable and entropy-burst chemical explosive materials. A detonable explosive material is a material that explosives with the aid of detonation while an entropy burst explosive material is a very sensitive energetic material that does not require detonation, but explodes through a spontaneous decomposition of its molecules into gaseous products. The invention also presents representative non-detonable, non-hazardous compositions of such simulants that can be safely and effectively utilized within a broad spectrum of biological and non-biological explosives detection programs, non-limiting examples being the training of biological search-and-detect creatures such as explosive detecting dogs and the calibration of electronic explosive detecting instruments that rely on the principles of vapor sampling for their operations.
