Densities, Sound Speeds, Excess Volumes, and Excess Isentropic Compressibilities of Methyl Acrylate + 1-Propanol (or 1-Butanol) + Hydrocarbons(n-Hexane, n-Heptane, Cyclohexane, Benzene, and Toluene) at 308.15 K

Densities and sound speeds of ten ternary mixtures of methyl acrylate (1)+1-propanol (2) or 1-butanol (2)+n-hexane (3), +n-heptane (3), +cyclohexane (3), +benzene (3), and +toluene (3) have been measured at 308.15 K. The excess volumes, V ^E , and excess isentropic compressibilities, ^E _s , have been estimated. These two experimentally derived excess functions were also compared with those predicted by empirical equations of Redlich–Kister, Kohler, and Tsao–Smith. A qualitative analysis of V ^E and ^E _s data of ternary mixtures reveals that in MA (1)+1-alcohols (2)+n-hexane (3), +n-heptane (3), and +cyclohexane (3), structure disruptions are more predominant while in MA (1)+1-alcohols (2)+benzene (3) or +toluene (3) mixtures, the weak but specific structure making interactions dominate. A perusal of deviations between the experimental and calculated V ^E and ^E _s results shows that the predictive expressions give only a rough estimate of the functions for the ten studied mixtures.
