abstract: This work presents an in-depth kinetic thermal degradation comparison between tra-ditional monocationic and the newly developed dicationic ionic liquid (IL), both coupled with a bromide (Br�) anion by using non-isothermal thermogravimetric analysis. Thermal analyses of 1-butyl-1-methylpyrrolidinium bromide C4MPyrBr and 1,4-bis(1-methylpyrrolidinium-1-yl)butane dibromide BisC4MPyrBr2  were conducted at a temperature range of 50�650�C and subjected to various heating rates, which are 5, 10, 15, 20 and 25�C/min. Thermogravimetric analysis revealed that dicationic IL, BisC4MPyrBr2  is less thermally stable compared to monocationic C4MPyrBr. A detailed analysis of kinetic parameters, which are the activation energy (Ea ) and pre-exponential factor (log A), was calculated by using Kissinger-Akahira-Sunose (KAS), Flynn-Wall-Ozawa (FWO) and Starink. This study revealed that the average Ea and log A of BisC4MPyrBr2  are lower than C4MPyrBr, which may be contributed to by its low thermal stability. Conclusively, it proved that the Ea and log A of ILs are strongly related to the thermal stability of ILs. © 2022 by the authors. Licensee MDPI, Basel, Switzerland.
