胺与2-氯-5-甲氧基对苯醌在乙腈中形成电荷转移络合物的研究

Formation of CTC by 2-chloro-5-methoxyl-p-benzoquinone and tertiary amines in acetonitrile

用“连续变化法”测出三乙胺、三正丁基胺与 2 氯 5 甲氧基对苯醌在乙腈中形成的基态电荷转移络合物(CTC)均以 1∶1相结合 ,并且用Hildebrand Benesi方程分别计算出CTC的平衡常数KCT、摩尔吸光系数εCT和形成CTC的能量变化ΔGCT。

The molar ratios of the charge transfer comlexs(CTC) formed by triethylamine or tri n butylamin with 2 chloro 5 methoxyl p benzoquinone in CH 3CN were all 1∶1 determined by a Continuons Variation Method. The equilibrium constant K CT , molar extinction coefficient ε CT of CTC and the free energy Δ G CT for formation of CTC were predicted by Hildebrand Benesi equation, respectively.
