Abstract N-methylmorpholine-N-oxide (NMMO) is widely used in cellulose solvents. In this paper, the thermal kinetics of NMMO was studied. First, the adiabatic decomposition experiment was carried out using the accelerating rate calorimeter (ARC), and the initial decomposition temperature of NMMO under adiabatic mode was 119.87 ℃. The apparent activation energy was 219.7 kJ·mol^-1 and the reaction order was 1 by kinetic calculation. Second, differential scanning calorimetry (DSC) was used to investigate the decomposition process at different heating rates, and the thermal kinetics parameters of NMMO were obtained by Friedman method, Flynn-Wall-Ozawa method and ASTM E698 method software AKTS. The initial decomposition temperature was 161.07—186.40 ℃, and the apparent activation energy of the three models were 81—134 kJ·mol^-1, 75.81—100.34 kJ·mol^-1 and 101.92 kJ·mol^-1, respectively, which were lower than those of the ARC experimental results. Finally, the risk level of NMMO thermal decomposition was three grade by the risk matrix method. The results provide theoretical basis for reducing risk in NMMO production, storage and transportation.
