Their compositions were determined after chemical analysis, IR spectrum study, thermogravimetric (TG) and differential thermal analysis (DTA). By using the RD496-2000 microcalorimeter, the standard enthalpies of formation of the synthesized compounds were obtained according to a pre-designed thermal cycle. Four sets of TG data with different heating rates (2.5 K·min~(-1), 5 K·min~(-1), 10 K·min~(-1) and 15 K·min~(-1)) were obtained. After the exploration of the kinetic data in the non-isothermal thermal decomposition process, the activation energy E, the logarithm of the pre-exponential factor ln A, the reaction order n, and the dynamical equation of the water loss step were derived. Ozawa method was also used to test the obtained dynamical data. 收起
