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.
Keywords:tetrachloro-p-benzoquinone  1-methylimidazole  charge transfer complex  Benesi-Hildebrand equation
