Summary, etc. <p style="text-align: justify;">The experimental values of ultrasonic speeds and densities, of binary mixtures of methyl acrylate with 1-butanol, 1-hexanol, 1-octanol and 1-decanol have been used to calculate the internal pressures, free volumes, excess internal pressures, excess free volumes, excess free energy, excess enthalpy and excess entropy of mixing over the entire composition range at 298.15 K using regular solution theory. The results have been interpreted in terms of intermolecular interactions between the component molecules in the mixture. The variations of these excess properties with composition indicate that the methyl acrylate-alkanol interaction in these mixtures follows the order: 1-butanol &gt; 1-hexanol &gt; 1-octanol &gt; 1-decanol. It is observed that the order of interactions in these mixtures depends upon the length of alkyl chain in the studied 1-alkanol molecules. In addition, the values of ultrasonic speeds have also been calculated theoretically for these mixtures using scaled particle theory and found to be in good agreement with experimental findings.</p>
