The non-isothermal decomposition kinetics of glycine was investigated using analyzer DTG-60. TG experiments were carried out under dynamic nitrogen atmosphere of 30 mL min(-1) with heating rates of 10, 14, 18 and 22 K min(-1). The kinetic parameters such as activation energy (E), exponential factor (A) and reaction order (n) were evaluated by Flynn-Wall-Ozawa, Doyle, Kissinger and Satava-Sestak methods. The results show that the non-isothermal decomposition mechanism of glycine corresponds to nucleation and growth, following the Avrami-Erofeev equation with n = 1/3. Moreover, thermodynamic properties of the non-isothermal decomposition process such as the change in the values of enthalpy (Delta H), entropy (Delta S) and Gibbs free energy (Delta G) were calculated.
