摘要: A conductance study concerning the association of Na+, K+, Rb+, and Cs+ with 1,13-dibenzo-24-crown-8 in acetonitrile has been carried out at 35, 30, 25, 20, 15°C. The observed molar conductivities Λ were found to decrease significantly for mole ratios less than unity. model involving 1∶1 stoichiometry used analyze conductivity data. stability constant, K, ΛC each complex determined from data by using a nonlinear least squares curve fitting procedure. binding sequence, based on value log K 25°C, is be Rb+>Cs+>K+>Na+. Values ΔHo ΔSo are reported their significance discussed.
