WebJan 10, 2009 · Abstract. The stability constant of the dibenzo-18-crown-6·H 3 O + cationic complex species dissolved in nitrobenzene saturated with water has been determined from extraction experiments in the two-phase water–nitrobenzene system and from γ -activity measurements. Various structures of protonated dibenzo-18-crown-6 are discussed.
