Changes of refractive indices of the ternary mixtures chlorobenzene +n-hexane + (n-nonane orn-decane) at 298.15 K

Abstract

The measures of the refractive indices of the ternary mixtures chlorobenzene þ n-hexane þ (n-nonane or n-decane) have been done at 298.15 K and atmospheric pressure in the whole composition diagram. The composition dependence of the derived magnitude has been compared with the data obtained with several theoretical models. Attending to the accurate results of these models, the equation of state enclosing mixing rules are pointed out as simple procedures for a multicomponent estimation of refractive indices, the corresponding binary parameters could be used to other thermophysical studies.

Ultrasonic velocity measurements for the ternary mixtures chlorobenzene +n-hexane + linear aliphatic alkane (C7–C8) at 298.15 K

“…1, the changes of isentropic compressibilities at each ternary mixture are showed as a function of solvent molar fraction, where the influence of the methylene group contribution difference can be observed. In what is referred to n-alkanes, the functional variation decreases the negative change of isentropic compressibility from n-hexane to n-nonane, progressively, as observed in our studies [18] and recent ternary experiments in our laboratory [10,24,25]. As it is observed in Figs.…”
