研究一种方法以测定二苯并-18-冠-6在氯仿中与碱金属苦味酸盐相互作用的若干参数. 这些参数是: 络合物的无限稀释摩尔电导A0, 络合物的解离常数Kd(或K1), 络合物中冠醚与盐的分子比, 冠醚对苦味酸盐的络合常数Ke(或Ke), 以及冠醚存在下苦味酸盐紧密离子对的饱和浓度[MA]等.

关键词: 碱金属, 冠式化合物, 苯 P, 氯仿, 离解平衡, 苦味酸, 络合常数

A method for determine some parameters in the interaction of dibenzo-18-crown-6 with alkali picrates in CHCl3 was examined These parameters are limiting molar conductances of the complexes, L0, complex dissociation constants, Kd, stoichiometric ratio of crown ether to picrate in the complex, complexation constant of crown ether with picrate, Kc, and saturation concentration of alkali picrate tight ion pair in the presence of crown ether, [MA].

Key words: ALKALI METAL, CROWN ETHER COMPOUNDS, BENZENE P, CHLOROFORM, DISSOCIATION EQUILIBRIUM, TRINITROPHENOL P, COMPLEX CONSTANT
