Crystallization of fatty acids for a lauric acid + myristic acid system from ethanol aqueous solutions, which extracted the fatty acids from their organic solutions, has been carried out. The mole fractions of lauric acid excluding solvent components in the aqueous solutions after the liquid-liquid extraction were a little higher than those in the organic solutions. As crystallizing of the fatty acids from the aqueous solutions proceeded, the crystals of the fatty acids floated on the surface of the aqueous solution, and the mole fractions of lauric acid in the crystals increased considerably from the mole fractions of lauric acid excluding solvent components in the aqueous phase. The effect of experimental conditions on the mole fraction of lauric acid in the crystals was shown.
