Reaction mode on the green construction process and corresponding thermal stability evaluation of ionic liquid

Ionic liquids (ILs) can be used as building materials, such as ILs polymers. Thermal stability is the basic attribute of selecting the most suitable high-temperature lubricant, fluid, and solvent compound for high-temperature organic reactions. The related literatures showing the thermal hazard of ILs at high temperature have been explored, but the analysis basis and evaluation reaction mode are lacking. This study combines reliable literature values of reaction parameters that no need for considering the complexity of reaction mode and nonlinear fitting that can calculate advanced reaction mode to follow the past literature flow and establish subsequent hazardous properties on ILs. A frequently used ILs, 1-butyl-3-methylimidazolium nitrate ([Bmmim]NO 3 ), was selected and measured by thermogravimetric analyzer. The weight loss data recorded by the instrument are combined with the thermodynamic equation to ascertain the reaction kinetics of [Bmmim]NO 3 . The kinetics is described the changes and trends of the overall reaction on which the influence of external temperature is brought into reaction system. The numerical model is constructed to evaluate the thermal hazards of a large number of substances in the actual environment with different container forms in 25.0 g and 50.0 g packages. The results show that [Bmmim]NO 3 has briefer period ( 270 °C).
