Hexane, limonene, 2-methylpropan-1-ol, hexan-1-ol, methyl isobutyl ketone, methyl tert-butyl ether and butyl ethanoate were tested. For hydrocarbons addition of de-emulsifier into the system (reduction of interfacial tension) was necessary. The highest yields were obtained with 2-methylpropan-1-ol – 67 % of total sterols and 89 % of β-sitosterol. Disadvantages of most of the tested solvents included the formation of the undesirable stable solid interphase, their partial solubility in water phase, high boiling point and/or instability. These properties complicate the treatment of tall oil soap by liquid-liquid extraction or the regeneration of the used organic solvent.
