Solvent Extraction and Oil Desolventizing - The extraction process consists of "washing" the oil from the soybean flakes with hexane solvent in a countercurrent extractor. 3. . Permeability of oilseeds 3. A chemical's retention factor during the process of thin layer chromatography is known by how far the chemical travels on the plate as per the movement of the solvent. A number of cardinal factors exert a positive influence on the phenomenon of solvent extraction, namely : (a) Effect of temperature and inert solutes, (b) Effect of pH on extraction, (c) Effect of ion-pair formation, and (d) Effect of synergistic extraction. Effect of Solvent It is known that solvents could influence the degradation of drugs depending on the solute-solvent interaction. Solvent. For example, it can be done by using solvent which is a desired substance dissolves in the extraction and the undesired substance does not dissolve. 3. 1 Solvent Extraction Based on separating aqueous phase from organic phase Used in many separations U, Zr, Hf, Th, Lanthanides, Ta, Nb, Co, Ni Can be a multistage separation Can vary aqueous phase, organic phase, ligands Uncomplexed metal ions are not soluble in organic phase Metals complexed by organics can be extracted into organic phase Industrial oil processing for the edible oil generally involves the solvent extraction step which may or may not be preceded by pressing. The solvent that is enriched in solute (s) is called extract. comprehensive monograph on solvent extraction in analytical chemistry [5].

Solvent Extraction of Oil from Seeds- Sunflowers track the Sun. Usually high molecular The extraction solvent hot or cold is then poured on top of the material, soaked, and kept for a short period of time (Ingle, 2017). Modifiers -these are the substances when added into aqueous phase, they increase the solubility of solute to be extracted into organic solvent. . The transfer is driven by chemical potential, i.e. extraction technology, plant material, manufacturing equipment, extraction method and solvent and the adherence to good manufacturing practices certainly help to produce a good quality extract. The Soxhlet extraction is an automatic continuous extraction method with high extraction efficiency that requires less time and solvent consumption than maceration or percolation. The process of extraction can be divided into five steps: Size reduction of drug Penetration of solvent into drug Dissolution of constituents Outward diffusion of solution from the drug . Generally, choice of solvent, amount of solvent, temperature, duration of extraction, external energy such as ultrasonic, microwave, supercritical, etc. The high temperature and long extraction time in the Soxhlet extraction will increase the possibilities of thermal degradation. The extraction solvent hot or cold is then poured on top of the drug material, soaked, and kept for a short period of time. Although bitumen is readily extractable by this method the overall process efficiency can be quite low because of substantial entrapment of solvent by the sand.
