用硝酸法由TADFIW制备HNIW
Preparation of HNIW from TADFIW in Nitric Acid
【摘要】 在82.48%~88.89%硝酸中,将四乙酰基二甲酰基六氮杂异伍兹烷(TADFIW)硝解为γ-六硝基六氮杂异伍兹烷(HNIW),得率88%以上,纯度99.4%以上。该方法最佳硝酸浓度为86.66%,此时HNIW得率94.0%,纯度99.51%。所得HNIW中所含的主要杂质为五硝基一乙酰基六氮杂异伍兹烷(PNMAIW),与TADFIW在硝硫混酸中硝解所得主要杂质五硝基一甲酰基六氮杂异伍兹烷(PNMFIW)不同,说明TADFIW在硝酸中硝解与在硝硫混酸中硝解的反应历程不同。
【Abstract】 γ-Hexanitrohexaazaisowurtzitane(HNIW) was obtained with the yield of more than 88% and the purity of larger than 99.4% by nitration of tetraacetydiformylhexaazaisowurtzitane(TADFIW) in 82.48%-88.89% nitric acid.The results show that the optimal concentration of nitric acid is 86.66% as the yield is 94.0% and the purity is 99.51%.The main impurity pentanitromonoacetylhexaazaisowurtzitane(PNMAIW)in HNIW prepared by this method was seperated and characterized,that is different from the main impurity pentanitromonoformylhexaazaisowurtzitane (PNMFIW)in HNIW from nitration of TADFIW in the mixture of nitric acid and sulfuric acid.It shows that nitration mechanisms in those nitrating environments are different.
