Excess molar volumes \{V{\^{ }}\{{$\backslash$}text\{E\}\}\} V E and excess refractive indices n-\{{$\backslash$}text\{D\}\}{\^{ }}\{{$\backslash$}text\{E\}\} n D E were calculated from the experimental data. Refractive index values for the binary mixtures were predicted by using Lorentz-Lorenz, Gladstone-Dale and Eykman equations. Excess molar volumes showed positive trend, whereas excess refractive indices showed negative trend over the entire range of temperatures and concentrations studied in the present research. {\^A}{\copyright} 2015 Akad{\~A}{\copyright}miai Kiad{\~A}3, Budapest, Hungary.} }
