Excess molar volumes and isentropic compressibilities were measured at 303.15 and 313.15 K over the whole range of composition for methyl methacrylate (MMA)-n-alcohol mixtures from density and sound velocities, respectively. Excess volumes for MMA-methanol and MMA-propanol were found to be negative for the entire range except at higher MMA concentrations. Positive excess volumes were, however, noted for MMA-butanol, MMA-pentanol and MMA-hexanol systems. The temperature coefficients of expansion at an ester mole fraction of 0.5 were estimated and observed to decrease with increase in the carbon chain-length of the alcohols. The excess isentropic compressibilities show a similar trend. The results are explained in terms of specific packing and non-specific dispersing interactions.
