This paper presents excess enthalpies for the following systems containing refined vegetable oils: soybean oil + methanol (at 353.15 K/722 kPa), soybean oil + ethanol (at 353.15 K/687 kPa and 383.15 K/653 kPa), soybean oil + n-hexane (at 353.15 K/722 kPa and 383.15 K/756 kPa), soybean oil + propan-2-ol (at 298.15 K/998 kPa), sunflower oil + methanol (at 353.15 K/791 kPa), sunflower oil + ethanol (at 353.15 K/894 kPa and 383.15 K/860 kPa), sunflower oil + n-hexane (at 353.15 K/756 kPa and 383.15 K/894 kPa), sunflower oil + propan-2-ol (at 298.15 K/929 kPa), rapeseed oil + methanol (at 353.15 K/963 kPa), rapeseed oil + ethanol (at 353.15 K/998 kPa and 383.15 K/1136 kPa), and rapeseed oil + n-hexane (at 353.15 K/894 kPa and 383.15 K/1136 kPa). The measurements were carried out with a commercially available isothermal flow calorimeter. The experimental H-E values have been correlated using the Redlich-Kister polynomial equation. The results for systems with propan-2-ol and some values of partial molar excess enthalpies at infinite dilution, H-i(E,infinity), obtained in this study have been compared to those available in the literature. The results were also discussed in terms of molecular interactions. (C) 2014 Elsevier B.V. All rights reserved. (AU)
