Thermal stability and decomposition mechanism of dicationic imidazolium-based ionic liquids with carboxylate anions

This work presents the synthesis, thermal stability, and decomposition mechanisms of the dicationic ionic liquids (DILs) [Bis(C n MIM)][C m COO] 2 (in which n = 4 and 10, and m = 3 and 6). Short-term thermal stability was determined using conventional thermogravimetric analysis, while long-term thermal stability was studied through the kinetic analysis of thermal decomposition, using isothermal and isoconversional methodologies to determine the...
