Progress in the development of high energy dense oxidizers based on CHNO(F) materials

摘要

Here we report about the synthesis of 15 selected compounds with positive oxygen balances Ω as potential high energy dense oxidizers. We focused mainly on carbonate derivatives, carbamates, nitrocarbamates, nitramines and tetrazoles in combination with the fluorodinitromethyl and trinitromethyl moieties. The prepared materials were characterized thoroughly using vibrational analysis (IR and Raman), multinuclear NMR spectrosco-py, mass spectrometry, elemental analysis as well as DSC measurements and single crystal X-ray diffraction. In addition, the performances regarding the specific impulse I_s were estimated by calculation using the EXPLO5 computer code, with heats of formation calculated at the CBS-4M level of theory, and room temperature densities obtained from pycnome-ter measurements. The sensitivities towards impact and friction were determined according to BAM standard methods, as well as a small scale electrostatic discharge test (OZM).
