Abstract Equilibria of mutual transformations of mono-, di-, and tri-alkylbiphenyls ( abp ) were investigated in the liquid phase at 308 to 423 K. On the basis of experimental equilibrium constants, values of ΔrHmo/(kJ·mol−1) and ΔrSmo/(J·K−1·mol−1) were calculated. Below are given correspondingly: reaction, compound and values for Et- bp (I), i-Pr- bp (II), and t-Bu- bp (III): 4- abp = 3- abp , I
摘要 研究了液相中单、二和三烷基联苯 ( abp ) 相互转化的平衡,温度为 308 至 423 K。根据实验平衡常数,ΔrHmo/(kJ·mol−1) 值和ΔrSmo/(J·K-1·mol-1)被计算。下面分别给出:Et-bp (I)、i-Pr-bp (II) 和 t-Bu-bp (III) 的反应、化合物和值: 4- abp = 3- abp , I, 0.23, 5.76 ; 二、(0.45±0.41)、(5.72±1.13);三、(0.48±0.53)、(4.83±0.53);2- abp = 4- abp , I, -3.3, -5.76; II、-12.6、-5.76;III、-15.4、-5.76;3,5-di-abp = 3,3'-di-abp, I, -0.1, 5.76; 二、(0±0.60)、(5.98±1.65);三、(-1.34±0.67)、(4.48±1.87);3
