Excess molar enthalpies,, and excess molar volumes,, of binary mixtures containing dimethyl carbonate, or diethyl carbonate, or propylene carbonate + benzyl alcohol, + 2-phenylethyl alcohol, and + 3-phenyl-1-propyl alcohol have been studied over the entire range of composition at 308.15 K and at atmospheric pressure using a flow microcalorimeter and a digital density meter. The values are positive, increasing as the chain length of aryl alcohol increases and showing a maximum varying from 1040 J·mol -1 (diethyl carbonate + benzyl alcohol) up to 1730 J·mol -1 (dimethyl carbonate + 3-phenyl-1-propyl alcohol). values are negative or positive with no definite trend. The mixture containing propylene carbonate + 2-phenylethyl alcohol shows an inversion of sign. All curves for mixtures containing dimethyl carbonate and diethyl carbonate are quasi-symmetrical, whereas those containing propylene carbonate are asymmetrical. Results were fitted to the Redlich−Kister polynomial. The results are qualitatively discussed in terms of molecular interactions.
