Abstract

This study concerns the determination of molar enthalpies of mixing for mixtures composed by acetates (ethyl acetate, propyl acetate, isopropyl acetate, butyl acetate and isobutyl acetate) and ketones (2-butanone, 3-pentanone and 4-methyl-2-pentanone) + corn oil at 25 °C and atmospheric conditions. In the design of heat transfer and process equipment employed in the oils and seed processing industry, the knowledge of enthalpy of the organic solvent–oil mixtures is a determinant factor. All the binaries show the same trend, a decrease of temperature is observed when the mixture is carried out. An effect endothermic takes place as consequence of the new reorganization of molecules. The aim of this study was therefore to calculate the heat capacities at constant pressure for the studied systems.
