Investigation of thermal decomposition kinetics of taurine

The non-isothermal thermal decomposition of taurine was investigated by means of thermogravimetric analysis (TG) and differential thermal analysis (DTA). The experimental data were treated using Flynn-Wall-Ozawa, Doyle, Kissinger, and atava-estak methods, respectively. The results show that the non-isothermal thermal decomposition mechanism of taurine is classified as phase boundary reaction, and the mechanism function is the Mampel Power law with n = 1. The forms of both integral and differential for the mechanism function are and , respectively. The activation energy and the pre-exponential factor are 167.88 kJ mol(-1) and 1.82 x 10(13)min(-1), respectively.
