Theoretical and Experimental Methods for Studying Volumetric Behavior of Binary mixtures Containing Normal Alkanols

In this paper, molecular interactions in the binary mixtures composed of a xylene and selected 1alkanol (1butanol up to 1octanol) were investigated by measurement of the density at T= 323.15 K. From the experimental data, excess molar volumes were calculated. Obtained data were interpreted based on the type and magnitude of the physicochemical interactions in the binary liquid systems. In this sense, PCSAFT was used to correlate the volumetric behavior of binary mixtures. The correlated values of the model were satisfactory and the obtained data are within the uncertainty region.
