REFRACTIVE-INDEXES AND SPEEDS OF SOUND OF BINARY-MIXTURES OF N-HEXANEWITH 1-ALKANOL AT THE TEMPERATURE 298.15 K

In this work experimental values for the refractive index n(D), speed of sound u, and isentropic compressibility k(S) of binary mixtures of n-hexane with (l-butanol, 1-hexanol, and l-octanol) at T = 298.15 K an d atmospheric pressure are presented. From the experimental values, th e corresponding excess and deviation values were computed (changes of refractive index, changes of speed of sound, and changes of isentropic compressibilities) using variable-degree polynomials to fit the data.
