| 摘要: 本文合成了铬(Ⅲ)的一个新的双核配合物Cr2(Nica)4Cl5(OH)(H2O)6(Nica表示烟酰胺.通过元素分析、摩尔电导、红外光谱、热重.对该配合物进行了表征,表明烟酰胺以吡啶氮与铬(Ⅲ)配位.文章对该配合物进行了热分解脱水非等温动力学研究,运用Achar法与Coats-Redfern法,推断出该热分解脱水反应为二级反应.其动力学方程为dα/dt=Ac-E/RT(1-α)2,动力学补偿效应表达式为InA=0.2992E-0.5682. |

| Abstract: A new dinuclcar or(Ⅲ)-Cr(Ⅲ)complex Cr2(Nica)4Cl5(OH)(H2O)6(Nica denotes nicotinamide)was prepared, its component was assigned on the basis of clement analysis, molar conductance, IR, UV and TG. Pyridine ring nitrogen-bond chromium(Ⅲ)complex has been Observed in the ligand of Nica. The kinetics of thermal dehydration was studied under non-isothermal condition. The kinctic data were analyzed by means of the Acbar method and the Coats-Redfern method. The results show that thermal dehydration reaction at first step is a second order reaction. The kinetic equation can be expressed as: dα/dt=Ac-E/RT(1-α)2.The mathematical expression of the kinetic compensation effect is found to be:InA=0.2992E-0.5682. |
