本文用量热法研究了四个4’-苯多烯酰基苯并-15-冠-5和一个4’-苯酰基苯并15-冠-5共五个三岔共轭化合物与四苯硼化钠在80％乙醇溶液中的配合反应热效应.通过计算得出配合反应的表观平衡常数K,以及有关的热力学函数的改变量.并用同系因子(1/a)~(2/N)(N=n+t)来考察这类化合物热力学函数间同系递变关系.经回归分析得同系直线方程为:logK=7.628(1/2)~(2/N)-5.349直线有一定的斜率,表明共轭主链的增长对冠醚基团的配合能力有较大的影响.即共轭主链的共轭作用可影响冠醚基团的配合性能.
In this paper, four 4’-benzo-15-crown-4 and 4-benzoyl-15- The apparent reaction constant K and the change of the thermodynamic function were calculated by calculating the thermal reaction of sodium in 80% ethanol solution. = n + t) to investigate the syngenetic relationship between the thermodynamic functions of these compounds. The regression equation shows that the linear equation of homology is: logK = 7.628 (1/2) ~ (2 / N) -5.349 The slope of the line has a certain slope The growth of the conjugated backbone has a greater impact on the ability of the crown ether groups to conjugate. That is, the conjugation of the conjugated backbone can affect the coordination properties of the crown ether groups.
