Catalytic ignition of ionic liquids for propellant applications
ABSTRACT In this proof of concept study, the ionic liquids, 2-hydroxyethylhydrazinium nitrate and 2-hydroxyethylhydrazinium dinitrate, ignited on contact with preheated Shell 405 (iridium supported on alumina) catalyst and energetically decomposed with no additional ignition source, suggesting a possible route to hydrazine replacements.

ABSTRACT: Energetic ionic liquids (EILs) are a subset of the rapidly growing field of ionic liquid research. These liquid and stable high-energy materials (HEMs) have many benefits, ranging from ease of manufacture and transportation to enhanced safety, as well as many new applications. This review focuses on the developments in this field from 2005 to 2012, with emphasis on propulsion applications of these new materials. Both bipropellant systems (hypergolic EILs) and monopropellant systems (oxygen balanced EILs) are discussed.05/2014; 2(22). DOI:10.1039/C4TA00204K
