Extraction Distribution of Sodium Picrate in the Water–Nitrobenzene System in the Presence of p-tert-Butylcalix[4]arene-tetrakis(N,N-diethylacetamide)

From extraction experiments with ²²Na as a tracer, the extraction constant corresponding to the equilibrium Na⁺(aq) + A^-(aq) + L(nb) ↔ NaL⁺(nb) + A^-(nb) taking place in the two-phase water–nitrobenzene system [A^- = picrate, L = p-tert -butylcalix[4]arene-tetrakis(N,N-diethylacetamide); aq = aqueous phase, nb = nitrobenzene phase] was evaluated as log K_ex(NaL⁺, A^-) = 4.6± 0.1...
