Definition
Liquid–liquid extraction is a method to
separate compounds based on their
relative solubilities in two
different immiscible liquids, usually water
and an organic solvent.
Process of Liquid-Liquid Extraction
Packed extraction column
Use in cases of
difficult physical
properties:
• Low density difference
< 50 kg/m3
• Low interfacial
tension: < 2 mN/m

Application In Industry
• Fractination of coconut oil
• High Boiling Organics
• Neutralization Acids / Bases





Fractionation of coconut oil

• In order to investigate the value of glyceride
structure of fats and oilsSolvent: ethanol
• Using the batch method and a continuous
counter-current extractor.
• Decreasing the lower fatty acids (caproic to
lauric) in the glyceride fractions.
