Relationships Between Molecular Structure and Chemical Reactivity in Hypergolic Ionic Liquids: Progress Toward Designing Green Fuels for Bipropellant Applications

Abstract

Hypergolic ionic liquids have the potential to replace the toxic and volatile hydrazine derivatives currently used as fuels in aerospace and missile propulsion systems. Now we present our results obtained in designing new hypergolic materials, and the impact of the properties of different anions upon the hypergolic reactivity and physical properties of ionic liquids. A new and efficient methodology to prepare hypophosphite (HP, 4) containing ionic liquids has also been developed. In addition, two anions that emulate the properties of the dicyanamide (DCA, 1) anion, the vinylogous dicyanamide (vDCA, 5) and N,N'-dicyanoformamidine (DCF, 6) have been used to prepare ionic liquids for hypergolic studies.
