Intramolecular Connections of Tetrazoles with N,N-Alkylene and Ether Bridges: Toward Energetic Materials with High Nitrogen and Thermal Stability
CRYSTAL GROWTH & DESIGN(2023)
摘要
To date, there have been few reports on fused tricyclic compounds in the field of energetic materials. To take full advantage of the high heat of formation of tetrazoles (334 kJ mol(-1)), a series of fused [5,6,5]- and [5,7,5]-tricyclic energetic compounds were synthesized by using 1,2-dibromoethane, 1,3-dibromopropane, and bromo(bromomethoxy)methane for intramolecular connections with bistetrazoles. In this study, the heat resistance of H2BTD (T-d = 318 degrees C) is the same as that of conventional heat-resistant explosive HNS (T-d = 318 degrees C). However, the fused tricyclic energetic compounds H2BTP (V-D = 8025 m s), H2BTD) (V-D = 7750 m s(-1)), and H2BTO (V-D = 8146 m s(-1)) exhibit higher detonation velocities than those of HNS (V-D = 7612 m s(-1)), making them potentially interesting candidates for further research into new heat-resistant explosives. The successful construction of fused [5,6,5]- and [5,7,5]-tricyclic compounds provides an effective guide for the future design of novel HEDMs.
