Thermochemical and Energy Characteristics of Dimers of Terfurazanoazepines

Abstract
The heat of combustion and the enthalpy of formation of 7,7 '-bis(terfurazan[3,4-b:3,4 '-d:3 '',4 ''-f]azepine (I) and 1,1 '-dioxide-7,7 '-bis(terfurazan[3,4-b:3,4 '-d:3 '',4 ''-f] azepine (II), were experimentally determined. Product I was studied by X-ray diffraction analysis, and its crystallographic characteristics were determined. The efficiency of using compounds I and II as components of solid composite propellants was analyzed, and the type of compositions in which they are more effective than HMX was determined.
