四乙酰基二甲酰基六氮杂异伍兹烷的硝解杂质与硝解机理

The Byproducts and Mechanisms of Nitrolysis of Tetraacetyldiformylhexaazaisowurtzitane

研究四乙酰基二甲酰基六氮杂异伍兹烷在浓硝酸和硝硫混酸介质中的硝解反应,两种介质体系中的主要硝解产物均为六硝基六氮杂异伍兹烷。采用柱色谱分离从两种硝解产物中得到了两种完全不同的杂质:前者为五硝基一乙酰基六氮杂异伍兹烷;后者为五硝基一甲酰基六氮杂异伍兹烷。硝解产物中存在不同杂质说明,四乙酰基二甲酰基六氮杂异伍兹烷在两种不同的硝解剂中发生的硝解反应遵循不同的硝解机理。

The studies of the nitrolysis of tetraacetydiformylhexaazaisowurtzitane in concentrated nitric acid and complex acid of nitric and sulfic acid were separetely made. The main products of nitrolysis of TADF in the two medium systems are both hexanitrahexaazaisowurtzitane. By use of colum chromato- graphy methods, two different nitration by-products obtained from the two medium systems were isolated, the former is monoacetylpentanitrohexaazaisowurtzitane and the latter is monoformylpentanitrohexaazaisowurtzitane. It is shown that reaction mechanisms of nitrolysis of TADF in concentrated nitric acid and complex acid of nitric and sulfic acid are different.
