which facilitates solvent extraction and decrease the volume of the equipment’s of the extraction respectively. In the case of rapeseed, due to high oil content, instead of expansion there is a pressing stage where 60 - 70% of the oil is removed. Oil Extraction The chemical oil extraction takes place in the extractor.

VEGETABLE OILS AS A SOLVENT FOR THE LIQUID LIQUID

oil and soybean oil can be used as a solvent for the extraction of isopropanol from isopropanol water mixture. Equilibrium data has been generated for isopropanol, water and vegetable oil ternary systems at room temperature and atmospheric pressure. Isopropanol is completely miscible with water as well as partially miscible with vegetable oil.
