Measurements of Density and Refractive Index of Soybean Oil + Short Aliphatic Alcohols

Densities and refractive indices of binary mixtures containing soybean oil+(methanol, ethanol, 1-propanol, 2-propanol, or 1-butanol) have been measured from 283.15 to 298.15K at atmospheric pressure, over the complete homogeneous composition range. Derived properties, such as excess molar volumes, partial excess molar volumes, and excess isobaric compressibilities, have been determined. Values of physical properties were compared with the results obtained by different prediction methods; the results were analyzed according to the non-ideality and large differences of molecular characteristics of the compounds included in this study.
