PROPERTY PREDICTION FOR BINARY AND TERNARY SYSTEMS WITH WATER, 1,4-DIOXANE AND ETHYLENE GLYCOL. II. REFRACTIVE INDEX

Binary and ternary mixtures containing water, 1,4-dioxane and ethylene glycol were studied in order to experimentally determine and to calculate the refractive index properties at different temperatures (293.15 K, 303.15 K and 313.15 K) of the entire range of composition.. Predictive equations such as Lorentz-Lorenz, Wiener, Heller, Gladstone-Dale, Arago-Biot and Edwards were used to calculate the refractive index properties and the accuracy of these methods was analyzed. The results can be used to obtain the property - composition curses for the studied mixtures with ethylene glycol. The Lorentz-Lorenz method with an advanced theoretical support can be used successfully for all systems.
