| 摘 要： | 研究了四氯苯醌(CA)与N-甲基咪唑(NMIm)在CH2Cl2中的基态作用 ,结果表明二者反应形成CA与NMIm的摩尔比为1∶1的电荷转移络合物(CTC) ,并采用UV-Vis、IR、及NMR进行了表征。应用Benesi-Hildebrand方程计算得到该CTC的平衡常数KCT=6.234× 10-2 L·mol-1,及摩尔消光系数εCT=8.442× 103(L·mol-1·cm-1)。

| Abstract: | The reaction of tetrachloro-p-benzoquinone (CA) with 1-methylimidazole (NMIm) in CH2Cl2 was investigated under ground state. The result showed that CA-NMIm charge transfer complex (CTC) was formed, and the molar ratio of the CTC was 1∶1 (CA∶NMIm). The CTC was characterized by UV-Vis,IR and NMR spectra. The equilibrium constant KCT(6.234×10-2L·mol-1) and molar extinction coefficient εCT(8.442×103 L·mol-1·cm-1) have also been calculated with Benesi-Hildebrand equation. |
