| 摘要 |
The formation of two crystalline forms of 2,6-bis (picrylamino)-3,5 dinitropyridine is accomplished by a purification method wherein needle-shaped crystals of 2,6-bis (picrylamino)-3,5 dinitropyridine are dissolved in dimethyl sulfoxide to form an adduct compound. Dissociating the adduct compound forms different crystalline structures of 2,6-bis (picrylamino)-3,5 dinitropyridine having improved properties.
