摘　　要：测定了六硝基六氮杂异伍兹烷(HNIW)在不同浓度硝酸中的溶解度及其随温度的变化。研究了将α、γ-HNIW在硝酸中转晶为ε-HNIW的工艺。结果表明,通过改变硝酸浓度、加晶种温度、搅拌速率可制备出具有不同结晶特性的HNIW。采用90%的硝酸进行HNIW的转晶,将加晶种温度控制在34～40℃,可以得到ε-HNIW,得率为98%以上,纯度为99%以上,酸值低于2‰。Solubility of hexanitrohexaazaisowurzitane （HNIW） and its changes with temperature in three kinds of different concentrations of nitric acid were measured. The process of crystal transition from α, γ-HNIW to ε-HNIW in nitrate acid was studied. ε-HNIW with different crystal quality were obtained by changing concentration of HNO3 , temperature of adding crystal seeds, stirring rate. ε-HNIW is obtained in 90% nitric acid when the temperature of adding crystal seeds is in the range of 34 - 40 ℃ . Its yield and purity is over 98% ,99% respectively, and acid number is below 2‰ （as HNO3 ）.
