  • Isolation and purification of sterols from neutrals fraction of tall oil pitch by single decantation crystallization
    Patent number: 6057462
    Abstract: Sterols from the solvent-extracted or distilled neutrals of saponified tall oil pitch are disclosed to be isolated and purified by a process of a liquid-liquid extraction where the hydrocarbon extraction stream is washed with an aqueous methanol solution to remove methanol-soluble impurities by adding the methanol and water, sequentially or as a blend. The resulting hydrocarbon/neutrals/methanol/water solution separates into an upper organic phase and a lower methanol/water phase, which lower phase is removed. The remaining organic phase is allowed to cool to from about 20-30.degree. C., with agitation, to facilitate crystallization of sterols, which crystals are recovered by filtering.
