| Abstract: | The molar ratios of the charge transfer comlexs(CTC) formed by triethylamine or tri-n-butylamin with 2-chloro-5-methoxyl-p-benzoquinone in CH3CN were all 1∶1 determined by a Continuons Variation Method. The equilibrium constant KCT , molar extinction coefficient εCT of CTC and the free energy ΔGCT for formation of CTC were predicted by Hildebrand-Benesi equation, respectively. |
