The oxidative azidation reactions of С nitro substituted saturated heterocyclic compounds, viz., the nitro derivatives of oxetane, azetidine, 1,3 dioxane, tetrahydro 1,3 oxazine, and hexahydropyrimidine, were investigated. A novel representatives of the geminal nitro azides were prepared and their physicochemical properties were studied. The process of the formation of the geminal dinitro compounds upon oxidative azidation was analyzed.
Combustion behaviours of melt‐castable explosives from azetidine family, 1,3,3‐trinitroazetidine (TNAZ), 3‐azido‐1‐nitroazetidine (AZNAZ) and 3‐azido‐1,3‐dinitroazetidine (AZDNAZ) have been studied. Burning rate measurements have been performed in a constant‐pressure bomb in the pressure range of 0.1–30 MPa. A pressure interval has been found within which pressed AZNAZ samples were incapable of sustained burning. Temperature profiles in the combustion wave of TNAZ, AZDNAZ and AZNAZ were measured using thin tungsten–rhenium thermocouples. Thermocouple‐aided measurements allowed the determination of the temperature dependence of TNAZ and AZDNAZ vapour pressure in a wide temperature interval, the boiling points at atmospheric pressure and the heat of evaporation. Combustion mechanisms of the energetic materials studied are discussed.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
