摘　　要：Lewis酸碱理论研究目前尚处于定性阶段,在环境化学上应用甚少,Gutmann等曾采用热力学与^(31)P NMR方法定量了少量有机溶剂的酸碱性,Kamlet等也利用^(19)F NMR测定了一些有机物的碱性.本文提出了一种利用多种溶剂/水分配系数来定量苯系物酸碱性的方法,该法简便、快速,有广泛的适用性。A new approach to the quantification of the Lewis acidity and basicity of benzene and its derivatives was presented in this paper.The logarithm difference values of partition coefficients of the compounds in butyl ether/water and in cyclohexane/water system were used as the measurement of the acidity,while the logarithm difference values of the partition coefficients in trichloromethane/water and tetrachloromethane/water systems were used as the measurement of the basicity.The experimental results show a good correlation with the values in literatures.In addition,an estimation method for basicity was also developed.
