合成了稀土氨基酸配合物晶体——三氯化缬氨酸六水合钕、钐,对合成样品进行了EDTA滴定、元素分析、红外光谱分析、热重、差热分析以及熔点测定,推测了配合物的热分解机理,采用Achar法和Coats-Redfern法研究了配合物热分解的非等温动力学过程,给出了各配合物样品失水阶段第一步反应和氨基酸骨架断裂阶段第一步反应的活化能(E)、指前因子的对数值(lnA)及热分解反应动力学方程式. Synthesis of a rare earth amino acid complex crystals - valine trichloride hexahydrate neodymium, samarium, the sample was titrated with EDTA, elemental analysis, infrared spectroscopy, thermogravimetry, differential thermal analysis and melting point determination of the complex Achar method and Coats-Redfern method were used to study the non-isothermal kinetics of the thermal decomposition of the complex. The first step of the dehydration step and the first step of the amino acid skeleton-breakage reaction were given Activation energy (E), logarithmic value of pre-exponential factor (lnA) and kinetic equation of thermal decomposition.
