The excess molar volumes, excess isentropic compressibility, excess in speed of sound, and deviation in viscosity data were fitted using a Redlich-Kister type equation. For the computed and experimental data, the standard deviation values are calculated. The viscosity data have been correlated with the equations of Tamura-Kurata, Grunberg-Nissan, Heric-Brewer, Hind et al., Katti-Chaudhri, and McAllister (four-body interaction) model. In addition, partial molar volumes of the 2-methyltetrahydrofuran with acetates have been determined in terms of the mole fraction concentration unit.
