Thermodynamics of 18-crown-6 complexes with ammonium cations (NH4, MeNH3, Me2NH2, Me3NH, Me4N, Et4N, PhNH3, and PhCH2NH3 ) in methanol were determined by titration calorimetry. The results show strong contributions from entropy terms counteracting th

A comprehensive study of complexation between potassium salts and 18-crown-6 in 14 different solvents shows stability constant K increases by >104 from water to pure methanol or to propylene carbonate (PC), with constants increasing in the order H2O
