✦ Synopsis

tion thermodynamics; micellization enthalpy; micellization heat We report a thermodynamic study of the aqueous solutions of 1capacity; nonideal thermodynamic properties; apparent and par-(3,3,4,4,5,5,6,6,6-nonafluorohexyl) pyridinium chloride, bromide, tial molar enthalpy; apparent and partial molar free energy; apparand iodide and N-octyl pyridinium iodide. Dilution enthalpies ent and partial molar entropy. and osmotic coefficients of the aqueous solutions of these cationic surfactants have been measured at 313 K as a function of the concentration. The experimental data are expressed in terms of
