【摘要】 本文用差热分析（DTA）、热重法（TG）、微商热重法（DTG）研究了十二种三价镧系金属离子与1,1,1,2,2,3,3七氟-7,7,二甲基-4,6辛二酮的络合物Ln（fod）₃·mH₂O的脱水过程和热分解过程的动力学。其脱水反应发生在100℃附近。络合物最大热分解速率的温度和热分解反应活化能均随中心金属原子——镧系元素原子序变化,呈现“双峰”现象。更多还原

【Abstract】 Thermal analysis was used to study the dehydration and the kineticprocesses of thermal decomposition of the complexes obtained from reaction of twelvekinds of trivalent lanthanide metal ions with 1,1,1,2,2,3,3-heptafluoro-7,7-dime-thyl-4,6-octadione. The results showed that the complexes were dehydrated first at about 100℃ andafterwards decomposed.The temperatures corresponding to the maximum rates ofthermal decomposition and activation energy were found to depend on the atomicnumber of the central metal atom,and there is a"double peak phenomenon"in thesecurves.更多还原
