“…The sound velocity u, isentropic compressibility s , as well as the fitting parameters corresponding to the binary mixtures enclosed into the studied ternary mixture were gathered in earlier papers [8][9][10][11]. Changes of isentropic compressibility for the ternary mixtures at the considered temperatures, which are shown in Tables 2 and 3, were computed applying the following equation: [18]; c [19]; d [20].…”

In this work, the applicability of the free length and the collision factor theories (FLT and CFT, respectively) to predict multicomponent changes of isentropic compressibilities is analysed and compared. To this end, appropiate expansions for ternary mixtures were derived from the original works, and then applied to a mixture containing unlike compounds in terms of functional molecular groups. Experimental data of excess molar volumes from open literature and new experimental isentropic compressibilities of the mixture chlorobenzene þ n-hexane þ (n-heptane or n-octane) were used to compute the parameters. A good accuracy was obtained when ternary prediction is attempted in this partially soluble mixture at different temperatures by the collision factor theory. These results show the versatility of this model for estimation in complex multicomponent mixtures with phases splitting. IntroductionSound velocity u and its related properties have been used to study physicochemical behaviour and molecular interactions in a variety of liquid mixtures. A survey of literature has shown that only a few measurements on the sound velocity and isentropic compressibility of multicomponent mixtures are available into open literature. Due to this fact, in the last few years, such quantities have been predicted by means of various semiempirical [1] or statistical mechanical theories [2-6], although in a whole part such studies are related to binary mixtures. Usually, large deviations for predictions of these properties are observed when biochemical, polar, or selfassociative molecules are envolved in multicomponent or partial miscible mixtures, due to the considerable non-ideal behaviour. In order to analyse this term, an attempt was made to evaluate as the free legth and the collision factor theories work in the prediction of ternary systems where complex interactions exist, as well as the effect of temperature in their estimation capability.

This article reports experimental values of speeds of sound, densities and refractive indices of mixing of the binary mixtures chlorobenzene þ (hexane, heptane, octane) at 288.15 K and 308.15 K and atmospheric condition. The corresponding derived properties were computed from the experimental data. Parameters of analytical expressions which represent the composition dependences of the derived properties are reported. Values of physical properties were compared with the results obtained by different prediction methods. The effect of temperature on the mixing is analysed in terms of the relative length of the alkyl chain.
