Abstract
Refractive indices of the six binary mixtures between N-Butyl bromide with Aniline, Benzene, Xylene, Carbon tetrachloride, n-Heptane and Toluene for the entire concentration range have been measured at 303.15 K. Furthermore, deviation in refractive indices from ideal mixture, molar refraction, deviation in molar refraction from ideal values for these mixtures has also been evaluated. The results are discussed in term of molecular interactions between the components of the binary mixtures.
Highlights
The studies of refractive indices are being increasingly used as tools [1,2,3,4,5] for investigation of the physical properties of pure components and the nature of intermolecular interaction between the liquid mixture constituents
Refractive index measurements of binary liquid mixtures are essential for determination of composition of binary mixtures usually for non-ideal mixtures where experimental measurements are performed directly over the entire range of composition
In the present study we have reported refractive index data for binary mixture of N-Butyl bromide with Aniline, Benzene, Xylene, Carbon tetrachloride, n-Heptane and Toluene for the entire concentration range
Summary
The studies of refractive indices are being increasingly used as tools [1,2,3,4,5] for investigation of the physical properties of pure components and the nature of intermolecular interaction between the liquid mixture constituents. The review of literature [6] on acoustical studies of solution reveals that refractive indices measurements are used to estimate the different elastic properties of the molecule from which the type of molecular interactions can be very well understood. Pandey et al [7] have made refractive indices measurements in liquid mixtures and have suggested that such studies are very much helpful for understanding of the molecular interactions in the components of the mixture. In addition to binary liquid mixtures, a few ternary, [8,9] mixtures have been studied employing refractive index measurements. Literature survey shows that study of molecular interactions between N-
