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.
