The method of vegetable oil bleaching by adsorption of impurities using activated bentonite involves the necessity of its regeneration. Studies on the yield of fatty impurities extraction by ethanol, isopropanol at the temperatures 35; 50; 65°C in alkaline medium at NaOH or KOH concentration range from 0.015 to 0.415 mole/dm³ of alcohol have been carried out. It was shown that ethanol solution with 0.323 mole/dm³ NaOH concentration is excellent extraction solvent.
