additives; ambient temperature; fuels; ionic liquids; liquids; oxidants
Abstract:
... A family of hydride-rich bis(borano)hypophosphite-based ionic liquids was developed, which showed good water stability at room temperature and unexpected hypergolic reactivity with oxidizers. These ionic fluids have exhibited the shortest ignition delay times so far, demonstrating their application potential as hypergolic fuels or additives in liquid bipropellants. ...

Abstract:
... In the development of advanced high-energy-density materials (HEDMs), the traditional strategy of integrating oxidant and fuel components into an organic molecule makes it very difficult to balance the energy and safety of materials. Herein, we present an intermolecular host–guest inclusion strategy for constructing advanced HEDMs with well-balanced energy and safety. By gradually introducing high ...

Subject:
ambient temperature; fuels; heat; hydrazine; infrared spectroscopy; ionic liquids; mass spectrometry; nuclear magnetic resonance spectroscopy; salts; thermal stability; vapor pressure; viscosity
Abstract:
... Two series of super-base-derived hypergolic ionic liquid materials were synthesized and fully characterized by ¹H and ¹³C NMR, IR spectroscopy, and high resolution mass spectrometry (HRMS). Their physicochemical properties such as thermal properties, density, viscosity, heats of formation, specific impulse, and ignition delay time were intensively characterized or calculated. Among fourteen new or ...

Abstract:
... A series of C–N linked bistetrazolate nitramino compounds, i.e., 1-(2H-tetrazol-5-yl)-5-nitraminotetrazole (2) and its energetic salts (3–8), were successfully prepared from readily available 5-aminotetrazole. All new energetic compounds were fully characterized by IR and NMR spectra and elemental analysis, and six of them (1, 3–7) were further determined by single-crystal X-ray diffraction analys ...
