Abstract
Abstract A novel explosive compound, 1,4,5,8-tetranitro-1,4,5,8-tetraazadifurazano[3,4-c][3,4-h]decalin is prepared by the reaction of 3,4-diaminofurazan and glyoxal in dilute hydrochloric acid, followed by the nitration of the intermediate 1,4,5,8-tetraazadifurazano[3,4-c][3,4-h]decalin. The nitrated compound has a higher density and detonation pressure and velocity than the known explosives HMX and HNB.
