New experimental thermodynamic data involving density, viscosity and ultrasonic velocity of the binary liquid mixture of methyl methacrylate with heptane-2-ol, octane-2-ol and decane-2-ol at 303.15 K temperature and at atmospheric pressure have been measured; these experimental values were correlated by Jouyban-Acree model. These basic parameters further used to evaluate excess molar volume, deviation in viscosity and deviation in isentropic compressibility of binary systems and these values were fitted to Redlich-Kister polynomial equation. The mixture viscosities were correlated by several semi empirical approaches like Hind, Choudhary-Katti, Grunberg-Nissan, Tamura and Kurata,McAllister three and four body model equations. The calculated excess molar volumes, deviation in isentropic compressibility were found to be positive and deviations in viscosity were found to be negative for all the binary liquid mixtures at both temperatures. The results were discussed in terms of molecular interactions prevailing in the mixtures.
