摘要高能量密度材料是一种能量存储材料，也就是我们所熟知的推进剂，发射药和炸药。这类高能材料主要应用于航天推进，武器发射与炸药爆破毁伤。2,4,6,8–四硝基-2,4,6,8-四氮杂双环[3,3,0]辛烷作为一种新型高能量密度材料，其能量密度高于1,3,5,7-四硝基-1,3,5,7-四氮杂环辛烷(HMX)，热安定性较好,潜在应用价值较大,故一直是国内外含(高)能材料(Energetic Materials)研究领域关注的焦点。本论文致力于合成两种双环HMX母体，其一是利用醛胺缩合合成2,4,6,8–四苄基-2,4,6,8-四氮杂双环[3,3,0]辛烷；另一个是以亚甲基二乙酰为起始原料，制备2,4,6,8–四乙酰基-2,4,6,8-四氮杂双环[3,3,0]辛烷，并对其结构进行表征。10848

Title Studies on the synthesis of bicyclic HMX precursor.
Abstract
The high energy density materials is an energy storage material, that is, we know propellants and explosives. Such high energy density materials is used in aerospace propulsion, weapons firing and blasting damage. 2,4,6,8-tetranitro-2,4,6,8-tetraazabicyclo [3,3,0] octane (bicyclic HMX) as a new type of high energy density materials,its energy density is higher than 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane (HMX), thermal stab-
ility is better,and the value of potential applications is great, it has been the focus of Energetic Materials research areas at home and abroad. This paper is dedicated to the synthesis of two bicyclic HMX precursor,one is the synthesis of 2,4,6,8-tetrabenzyl-2,4,6,8-tetraazabicyclo [3,3,0] octane by condensation of aldehydes,indluding glyoxal,with amines; another is based on methylene bisacetamide as raw materials, preparation of 2,4,6,8-tetranitro-2,4,6,8-tetraazabicyclo [3,3,0] octane, and their structures were characterized.
