Thermal Stability of Ionic Liquids: Current Status and Prospects for Future Development

Ionic liquids (ILs) are the safest solvent in various high-temperature applications due to their non-flammable properties. In order obtain thermal stability properties, thermogravimetric analysis (TGA) is extensively used analyze kinetics of decomposition process. This review summarizes different methods and finds isoconversional superior Arrhenius calculating activation energy, two tools—the compensation effect master plots—are suggested for calculation pre-exponential factor. With both parameters, maximum operating temperature (MOT) can be calculated predict long-term runnings. The collection data ILs with divergent cations anions shows structure such as alkyl side chains, functional groups, substituents will affect stability, but influence less than that anions. To develop dicationic (DILs) recommended, typically, [C4(MIM)2][NTf2]2 has a high 468.1 °C. For convenience application, on energy 130 summarized at end this manuscript.
