ABSTRACT

In this work experimental data for the refractive index on mixing for butyl acetate + (toluene, ethylbenzene, p-xylene, isopropylbenzene, butylbenzene, isobutylbenzene, mesitylene, or t-butylbenzene) binary mixtures, and some computed derived properties, as a function of temperature, are presented. The mixtures show a clear expansive trend for the highest molar mass compounds. Values of measured properties were compared with results obtained by semiempirical relations and equations of state with simple mixing rules. Accurate results were obtained with the latter, and such parameters could be used in the prediction of multicomponent refractive indices or other thermodynamic properties using standard thermodynamic expressions.
