Dicyanoborate-Based Ionic Liquids as Hypergolic Fluids

摘要

Hypergolicity, the spontaneous reaction of one chemical (fuel) when contacted with another (oxidizer), is not a new concept since suitable reactions have been reported where a very large variety of liquid-liquid, liquid-solid, and solid-solid combinations were and persist in being employed. In propellant systems, the fuels of choice continue to be hydrazine and its derivatives although they are a class of acutely toxic and carcinogenic substances, and have high vapor pressures so that costly safety precautions and handling procedures are required.
