<div><p>Density and speed of sound data for (Methyl Benzoate + 1-Propanol), (Methyl Benzoate + 1-Butanol) and (Methyl Benzoate + 1-Pentanol) have been determined at temperatures = (303, 308, 313, 318 and 323) K. From this data, excess parameters like excess volume, V<sup>E</sup>, excess isentropic compressibility, , and excess intermolecular free length, , have been computed. The variations of these parameters with composition and temperature of the mixtures are discussed in terms of molecular interactions in these mixtures. The values of and for all the systems under study are negative.</p></div
