【 摘 要 】

A comparative study of refractive index of binary liquid mixtures such as Cyclohexane+O-xylene, PEG200+Water, PPG400+toluene having industrial applications are analysed at temperature 303K for different concentrations [0 to 1%]. In the present study experimental values are taken from literature and there values are compared with theoretical values obtained by various mathematical equations such as Lorentz - Lorenz relation, Gladstone- Dale equation, Weiner's relation, Heller's (H) equation, Arago-Biot equation. Thus the present study reveals the nature of interaction between component molecules in the mixtures and enables us to identify a suitable mathematical model for predicting the refractive index of various binary liquid mixtures.
