Document Type and Number:
WIPO Patent Application WO/1999/041272
Kind Code:
A1
Abstract:
A method of isolating a purified tall oil sterol from neutral tall oil components, characterized by: (a) contacting the neutral tall oil components with at least one solvent selected from the group consisting of methanol, hydrous methanol, hydrous ethanol, hydrous isopropanol, and hydrous n-propanol at a temperature exceeding the boiling point at ordinary pressure of the solvent; (b) removing the matter remaining undissolved in the solvent from the resultant mixture; and (c) crystallizing the tall oil sterol from the solution obtained and recovering the crystals by filtration. By this method, a high-purity tall oil sterol can be easily isolated from neutral tall oil components.
