Abstract

In this research work pyrolysis characteristics of 1-propyronitrile imidazolium trifluoroacetate was studied using non-isothermal thermogravimetric analysis (TGA). Pyrolysis experiments were conducted in inert condition at three heating rates; 10, 20, and 30°C/min. The value of activation energy (Ea) and pre-exponential factor (A) were calculated by Kissinger–Akahira–Sunose (KAS) methods were 173.18 KJ/mol and 5.40×1016 s -1, while, the Ea and A calculated from Flyyn-Wall-Ozawa (FWO) and Starink methods were 172.48 KJ/mol and 173.44 KJ/mol, and 4.53×1016 s-1 and5.77×1016 s-1, respectively. The results presented that the values of kinetics parameters calculated by these three methods are in close agreement with each other.
