摘要
针对硝硫混酸硝解-转晶两步法制备ε-HNIW的现状,本文采用绿色硝化剂N2O5/HNO3硝解2,6,8,12-四乙酰基-2,4,6,8,10,12-六氮杂四环-[5,5,0,03,11,05,9]十二烷(TAIW)一步法直接制备ε-HNIW,并采用NMR、MS、XRD对其结构及晶型进行鉴定。ε-HNIW得率82.72%,纯度98.24%。该方法不仅避免硫酸的使用,减轻了废酸污染,而且在硝化液中直接转晶,简化了工艺路线,具有较强的应用前景。
ε-HNIW was synthesized by one-pot nitrolysis of 2, 6, 8,12-tetraacetyl-2, 4, 6, 8, 10, 12-hexaazatetracyclo[ 5, 5, 0, 0^3,11 ,0^5,9] dodecane （TAIW） with N2O5/HNO3 as the nitrating agent, which overcame the drawbacks of mix acid-nitrolysis and two step-crystal transformation. Structure and crystal form of ε-HNIW were characterized by NMR, MS and XRD. Yield of ε-HNIW is 82.72% , and its purity is 98.24%. By the use of new nitrating agent, the reaction eliminated the use of concentrated sulfuric acid and was eco-friendly. Moreover, ε-HNIW was directly transformed in the solution. The simplified process route shows good prospect in industry.
