| titleOfInvention | Method for producing sterols |
| abstract | <P>PROBLEM TO BE SOLVED: To provide a method for producing sterols in simple operations without using a special apparatus, while preventing the formation of wastes. <P>SOLUTION: This method for producing the sterols from a tall pitch is characterized by comprising (I) a process for passing a non-polar solvent solution of the tall pitch through the first adsorption column filled with an inorganic adsorbent to adsorb the polar substances to the inorganic adsorbent, (II) a process for reacting sterol esters contained in the polar substance-removed tall pitch with a lower alcohol in the presence of a catalyst to release sterols which are polar substances, (III) a process for distilling away the lower alcohol, adding the released sterols to a non-polar solvent, and passing the obtained solution through the second adsorption column filled with an inorganic adsorbent to adsorb the released sterols to the inorganic adsorbent, and (IV) a process for eluting the sterols from the inorganic adsorbent with a polar solvent. <P>COPYRIGHT: (C)2008,JPO&INPIT |
