摘　　要：四乙酰基二苄基六氮杂异伍兹烷(TADBIW)是制备六硝基六氮杂伍兹烷(HNIW)生产成本最低的硝解基质。本实验研究了由TADBIW制备HNIW时,HNIW晶型转变过程:硝解生成的是αHNIW,后者在高温硝解系统中逐渐转变为γHNIW,完成这种转变在70～75℃需3h,但晶体诱导体的加入能够加速这种转变。Tetraacetyldibenzylhexaazaisowurtzitane （TADBIW） is the cheapest nitrolysis substrate for synthesizing hexanitrohexaazaisowurtzitane （HNIW）. The process of crystal transformation of HNIW during nitrolysis is studied. Results show that α-HNIW is obtained from nitrolysis at high temperature, and it can be transformed into γ-HNIW gradually, the crystal transformation can be completed within 3 h at 70～75 ℃and speeded up by the additon of γ-HNIW crystal seeds in the nitrolysis system.
