Abstract: The thermal decomposition of abietic acid in air was investigated under non-isothermal condition using thermogravimetric analysis-differential thermal analysis (TGA-DTA) technique with heating rates of 5, 10, 15 and 25 K·min-1. The non-isothermal kinetic parameters were obtained via the analysis of the thermogravimetric and differential thermogravimetric (TG-DTG) curves by using Flynn-Wall-Ozawa method and Kissinger method. The thermal decomposition mechanism of abietic acid was studied with four integral methods (Šatava-Šesták, MacCallum-Tanner, ordinary integral and Agrawal). The results show that the thermal decomposition mechanism is nucleation and growth, and the mechanism function is Avrami-Erofeev equation with n equates 1/2. The activation energy and the pre-exponential factor are 64.04 kJ·mol-1 and 5.89×105 s-1, respectively.
