Excess molar volumes of binary and ternary mixture of sunflower Biodiesel, diesel and 2-Propanol at 293.15–353.15 K and ambient pressure

Abstract

The density of the pure components (2-Propanol), pseudo-components (sunflower Biodiesel and diesel) and pseudo-binary mixtures of sunflower Biodiesel with diesel (or +2-Propanol) and pseudo-ternary mixture of sunflower Biodiesel and diesel and 2-Propanol, were measured at different temperatures (293.15, 313.15, 333.15 and 353.15K) and ambient pressure, over the entire composition range (mole fractions from 0.0 to 1.0). The density of binary and ternary mixtures increasing by adding Biodiesel as a part of solute but the density was decreased with increasing temperature linearly. Based on density measurements, volumetric properties including excess molar volumes, partial molar volumes, partial molar excess volumes and their infinite dilution values, for these mixtures have been determined. Excess molar volumes were correlated with the Redlich–Kister polynomial expansions. Excess molar volumes show positive, negative behavior or integration of both values in two systems studied. According to obtained data, the Redlich-Kister model is a suitable model for these studies.
