Abstract

Excess molar volumes VmE(T = 298.15 and 318.15 K, x), measured with a tilting dilution dilatometer, are reported for {(1−x)CH3CH2CO2H+xCF3CO2H}(l). The excess volumes are negative over the entire composition range with negative derivatives with respect to temperature. An outstanding feature of the results is the fact that the curve of excess volume against mole fraction exhibits one maximum and two minima at each temperature. Partial molar volumes, evaluated from a polynomial fitted to the results, are graphically presented as well.
