固相化学反应研究(Ⅶ) 反应截面移动法研究氯化镍与H_2DMG的固相配位反应

INVESTIGATIOiN OF SOLID STATE REACTION OF NiCl_2· 6H_2O AND H_2DMG BY INTERSECTION FACE MOVING MATHOD

用反应截面移动法研究了氯化镍与H_2DMG的固相配位反应。首次提出了用反应截面移动法计算等温固相反应动力学参数的方法,推测了可能的反应机理。

Intersection face moving method is designed to study the solid state reaction of NiCl2 · 6H2O and H2DMG at 60℃. The Kinetics isothermal solid state reaction is investigted by using the intersection face moving method. The kinetics of this system conforms to a D2 mechanism,the activation energy is calculated as Ea=106.0±0. 2KJ· mol-1。
