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).
炸药 2,6-双(吡啶氨基)-3,5-二硝基吡啶的制备方法是
(a) 2,6-二氨基吡啶在极性原溶剂中与至少一种通式如下的化合物反应
其中
X 为卤素或含 1 至 4 个碳原子的烷氧基,但当 X 为卤素时,至少有一种选自碱土金属碳酸盐和碱金属碳酸氢盐的碱材料,其含量至少相当于所述化合物的一个摩尔当量、
(b) 过滤步骤(a)的反应产物;以及
(c) 在约 32°F (0°C) 至约 85°F (30°C) 的温度范围内,用至少 90% 的硝酸硝化步骤 (b) 的过滤反应产物。
