ABSTRACT

Experimental density and the refractive index of the ternary mixture acetone + n-hexane +water, and their binary systems were experimentally measured and correlated at 298.15K and atmospheric pressure. A maximum in refractive indices has been observed for the acetone +water system while the excess molar volume and the molar refraction change are all negative. For the mixture acetone + n-hexane, the excess molar volume is always positive and the molar refraction change of mixing showed a S-shaped dependence on acetone composition. The excess molar volumes and molar refraction changes of mixing were correlated using the Redlich Kister expression and Cibulka equation. The coefficients and standard deviation between the experimental and fitted values were estimated. Good agreement between both results was obtained.
