Abstract: Refractive indices of the binary liquid mixture of 1, 4-dioxane with 1-hexanol have been evaluated at T=(298.15, 303.15,308.15,313.15 and 318.15) K over the entire composition range using Abbemat referometer.  A comparative study on various mixing rules viz., Arago-Biot (A-B), Gladstone-Dale (G-D), Newton’s (Nn), Eyring and john (E-J), Lorentz-Lorentz (L-L), Heller (H), Eykman (Eyk), Oster (Os) and Weiner (W) relations to predicte the refractive index of the binary mixture at five studied temperatures calculated theoretically and the results discussed in terms of average percentage deviations.  Further, the excess refractive indices have been computed and fitted to the Redlich-Kister polynomial equation to derive the binary coefficients and standard errors.
