摘要：

From extraction experiments and gamma-activity measurements, the extraction constant corresponding to the equilibrium Na+(aq)+HL+(nb)reversible arrow NaL+(nb)+H+(aq) taking place in the two-phase water-nitrobenzene system (L = 18-crown-6; aq = aqueous phase, nb = nitrobenzene phase) was evaluated as log K-ex(Na+,HL+) = 0.1. Further, the stability constant of the 18-crown-6-sodium complex in nitrobenzene saturated with water was calculated: log beta(nb)(NaL+) = 8.0.
