Abstract

The densities and speeds of sound for ternary mixtures of methyl methacrylate (MMA) + 1-alkanols (1-butanol, 1-pentanol, 1-heptanol) + aromatic organic solvents (benzene, toluene, p -xylene, and ethylbenzene) or + cyclohexane have been measured at T /K = (298.15 and 308.15). Excess molar volumes and excess isentropic compressibilities were calculated across the mole fraction range, and the same were compared with the values calculated using similar data for the binary pairs through Redlich−Kister (RK), Tsao and Smith (TS), and Kohler (K) equations. As compared to others, the RK equation predicted the excess molar volumes and excess isentropic compressibilities adequately.
