由TADBIW合成HNIW

Synthesis of HNIW from TADBIW

为降低HNIW的合成成本,节省钯催化剂用量,以六苄基六氮杂异伍兹烷(HBIW)的一次氢解产物四乙酰基二苄基六氮杂异伍兹烷(TADBIW)作为反应基质,采用市售无机试剂使TADBIW分子上的两个苄基脱掉,实现了无钯脱苄的目的,分别合成出了四乙酰基二亚硝基六氮杂异伍兹烷(TADNSIW)和四乙酰基二硝基六氮杂异伍兹烷(TADNIW),得率分别为80.0％和70.6％;由TADNSIW经氧化、硝化合成了六硝基六氮杂异伍兹烷(HNIW),得率为96.2％,HNIW的纯度达到98.0％以上;由TADNIW和100％硝酸反应合成HNIW,得率为96.0％,纯度高于98.0％;由TADBIW采用一锅煮合成了HNIW,得率为82.2％,纯度在98.0％以上。

To reduce the cost for producing hexanitrohexaazaisowurtzitane ( HNIW), inorganic materials available from market readopted to remove two benzyls to prepare tetraacetyldinitrosohexaazaisowurtzitane (TADNSIW)and tetraacetyldinitrohexaazaisowurtzitane(TADNIW)as the precursors for synthesizing HNIW from tetraacetyldibenzylhexaazaisowurtzitane(TADBIW), with the yield of 80.0% and 70.6% respectively. HNIW is synthesized from TADNSIW with the yield of 96.2% and 96.0% respectively,and with the purity of higher than 98.0% .Preparation of HNIW from TADBIW can be also performed by one- pot method in larger scale,with the yield of 82.2% and purity higher than 98.0% .
