溴化镝丙氨酸配合物热分解反应的热分析研究

Application of thermal analyse to the study of decomposition of complexe of dysprosium bromide with alanine

在非等温条件下,采用DSC法研究了DyBr3·3Ala·2.5H2O配合物的热分解动力学,计算了热分解过程的活化能;分析了升温速率为10 k/min的DSC曲线,获得了热分解过程相应的动力学参数(E、InA)及可能的热分解机理及机理函数.

The kinetics of decomposition of complexes of dysprosium bromide with alanine was studied under non-isothermal conditions by DSC techniques, the activation energise(E) calculated by the Ozawa method and the kissinger method on the basis of the peak temperature of DSC cure, we dealt with the foundamental kinetic data by the Archar differential method and the Coast-Redfem integral method. ,The kinetic parameters (activation energy E,pre-expontial factor A and reaction order n) and the most probable mechanisms of thermal decomposition(β=10k/min)were obtained.
