摘要
Abstract
A new refining process of 2,6-diamino-3,5-dinitropyridie-1-oxide( ANPyO ) was investigated including acylation, recrystallization and deprotection procedures. The influence of different processing conditions on product purity,particle size dis-tribution,impact sensitivity,friction sensitivity and micro-structure were studied and compared with that of refining method with CF3COOH. Results show that the optimal conditions of new refining method are as following:DMF as solvent for the recrystalliza-tion of the intermediate(2,6-diacetamino-3,5-dinitropyridine-1-oxide)and ammonia as the amination agent and amination tem-perature 50 ℃. Under the conditions,ANPyO was prepared with yield of 90. 5%,and the purity of 99. 5% . Its properties were characterized with pH of 6.3,melting point of 355 ℃,vacuum stability of 0.01 mL·g -1,impact sensitivity of 257 cm,friction sensitivity of 2%.关键词
