Densities for mixtures containing sunflower seed oil with pentane, hexane, heptane, and octane have been determined at various temperatures between 298.15 K and 313.15 K using a vibrating tube densimeter. The derived excess volumes have been correlated by the Redlich−Kister equation. All the systems showed negative deviations from ideality. The excess volumes increased with an increase in temperature.
