An evaluation of anion suitability for use in ionic liquids with long-term, high-temperature thermal stability

Abstract

The stability of fourteen different PPN⁺ salts has been studied in 96 hour tests, in air, at temperatures of 200 °C, 250 °C, and 300 °C. The results have enabled generation of a ranking of their stabilities, and by extension, that of their anionic components. This data should prove especially useful in ongoing efforts to formulate ionic liquids for high-temperature applications.
