Densities, sound speeds, excess volumes, and excess isentropic compressibilities of methyl acrylate plus 1-propanol (or 1-butanol) plus 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, kappa(s)(E), 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 kappa(s)(E) 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 kappa(s)(E) results shows that the predictive expressions give only a rough estimate of the functions for the ten studied mixtures.
