ABSTRACT
The densities of (acetophenone + benzene, or toluene, or 1,3-xylene, or 1,3,5-trimethylbenzene) were measured at temperatures (298.15 and 328.15) K by means of a vibrating-tube densimeter. The excess molar volumes V E m calculated from the density data show that the deviations from ideal behaviour in the systems studied (all being negative) become more negative as the temperature is raised. The V E m results were correlated using the fourth-order Redlich Kister equation, with the maximum likelihood principle being applied for the determination of the adjustable parameters.
