Abstract
The standard thermodynamic parameters Δr G° Δr H° TΔr S° of the reaction of molecular complex formation between 18crown6 ether 18C6 and lphenylalanine Phe Phe18C6 have been obtained from calorimetric titration experiments carried out by means of the microcalorimetric system TAM III TA Instruments USA at T = 29815 K in water–dimethylsulfoxide H2O–DMSO solvents Results show that the increase of the DMSO concentration in the mixed solvents brings about an increase of the Phe18C6 complex stability and of the exothermicity of the reaction of complex formation
