The densities and excess molar volumes (V^E) fortri-n-octylamine (TOA) + propionic acid, TOA +diluent,and propionic acid + diluent binary systems were measured under thefull range of composition at 298.15K, respectively. The excess molar volumes of TOA + propionicacid + diluent ternary systems were alsomeasured at 298.15 K. Benzene, toluene, p-xylene,ethanol, hexane, and cyclohexane were used as thediluent.

Themaximum values of excess molar volume(als/jceaax/42/i02/eqn/je9601671e10002.gif">)for the ternary systems showed smaller values thanthat of TOA + propionic acid.
