摘　　要：研究了四氯苯醌 (CA)与N 甲基咪唑 (NMIm)在CH2 Cl2 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 2 34× 10 -2 L·mol-1,及摩尔消光系数εCT=8 4 42× 10 3 (L·mol-1·cm-1)。The reaction of tetrachloro-p-benzoquinone (CA) with 1-methylimidazole (NMIm) in CH 2Cl 2 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 K CT(6.234×10 -2?L·mol -1) and molar extinction coefficient ε CT(8.442×10 3?L·mol -1·cm -1) have also been calculated with Benesi-Hildebrand equation.
