From extraction experiments and γ-activity measurements, the extraction constant corresponding to the equilibrium H3O+(aq) + 1•Na + (nb)⇔ 1•H3O + (nb) + Na + (aq) taking place in the two-phase water–nitrobenzene system (1 = hexaethyl calix[6]arene hexaacetate; aq = aqueous phase, nb = nitrobenzene phase) was evaluated as log Kex(H3O+,1•Na + ) = 0.0± 0.1...
Keywords: hydroxonium cation, calixarene compound, Water–Nitrobenzene System, DFT study, structure of protonated calixarene
