【Abstract】 The kinetic characteristic parameter of thermal decomposition of sodium percarbonate with/without stabilizer are calculated according to the Coats and Redfern’s linearized simple graphical procedure. It is shown that the reaction order is 0.2; the activation energies are 183.9 kJ/mol and 162.5 kJ/mol and the frequency factors are 2.15×10 20 s -1 and 9.12×10 18 s -1 respectively. The higher stability of sodium percarbonate with stabilizer is affirmed by kinetic parameters.更多还原
