Refractive index, molar refraction deviation and excess molar volume of binary mixtures of 1,4-dioxane with carboxylic acids

Density, Speed of Sound, and Refractive Index Measurements for the Binary Mixture (1, 4-Dioxane + Isobutyric Acid) at T = (295.15, 298.15, 301.15, 304.15, 307.15, 310.15, and 313.15) K

“…53,54 The variation of excess speed of sound c E , excess isentropic compressibility κ S E , excess refractive index n E , and molar refraction deviation ΔR were correlated with the Redlich− Kister equation (eq 2), for the studied mixture. The coefficients A k , and standard deviations σ, obtained for this system at different temperatures are reported in Table 4.…”

Simple corrections for the static dielectric constant of liquid mixtures from model force fields

“…This infinite frequency correction to the static dielectric constant can be quantified using the refractive index. In fact, the index of refraction has been explored as a manner to experimentally determine 74 the excess molar volumes of the different components in a solution, such as in alcohol-water mixtures 75 , hydrocarbon-alcohol mixtures 76 , and other solutions [77][78][79] .…”

Investigation on thermophysical and excess properties of binary mixtures of imidazolium based ionic liquids at temperatures (293.15 to 323.15) K: III [C n mim][PF 6 ] ( n = 4, 6, 8) + THF

“…Refractive index of the binary mixtures were predicted using the pure component refractive index data by several predicting mixing rules such as Gladstone-Dale (G-D) [62], Arago-Biot (A-B) [63], Heller (H) [64], Weiner (W) [65], Oster (Os) [66], Newton (N) [67], Lorentz-Lorenz (L-L) [68], and Eykman (EK) [63]. Predicted values have been compared with the experimental refractive index through standard deviation (SD) and summarized in table 6.…”
