Key Words: Hexane, kinetics, oil extraction, sulfuric acid, sunflower seed, thermodynamics. Introduction There are several techniques for removing oil from oilseeds, including the wet process, the dry process, and solvent extractions. For many years, commercial-grade hexane has been the solvent of choice for the extraction of oil from oilseeds.
