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 <CHEM> 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 DEG F (0 DEG C) to about 85 DEG F (30 DEG C). |
