Using integral and differential methods based on model-free isoconversional methods, the kinetic parameters (the apparent activation energy Ea, the pre-exponential factor A and the most probable kinetic model function) of the dehydration decomposition for solid compound C8 H5O4NNa2· H2O were obtained by means of DSC techniques at four different heating rates. The most probable kinetic model function of the dehydration decomposition is related to chemical reaction, the apparent activation energy Ea is 200.22 kJ/mol and the pre-exponential factor A is 3.63×10^22/s.
