  • Publication number: 20120130100
    Abstract: The invention is related to a process for production of lignoceric acid from mixtures of long-chain aliphatic alcohols that contain lignoceric alcohol, wherein the process consists in oxidizing the mixture in a biphasic catalytic system using quaternary ammonium peroxotungstophosphate as a catalyst and hydrogen peroxide as an oxidant, followed by several physical or chemical unitary steps to separate and purify the lignoceric acid.

  • Patent number: 7087402
    Abstract: The present invention is related to a process for selectively transesterifying stanols in mixtures comprising sterols and stanols, and a process for separating sterols from said mixtures. The process of selective transesterification comprises the forming of a reacting mixture by contacting a selective lipase with a reactant mixture comprising sterols and stanols and an ester selected from the group consisting of esters of an organic acid with a short chain aliphatic alcohol. The transetrifying is carried out agitated reactors at pressures below atmospheric pressure and temperatures from 30 to 90° C.

  • Patent number: 7078544
    Abstract: A process for producing steryl or stanyl esters, comprises the steps of: a) forming a reacting mixture by contacting a lipase with a reactant mixture wherein the reactant mixture comprise sterols or stanols and one or more esters selected from the group consisting of esters of a fatty acid with a short chain aliphatic alcohol; b) separating the lipase from the reacting mixture to form a reacted mixture; and c) separating steryl or stanyl esters from the reacted mixture. The reaction is carried out in stirred reactors at pressures below atmospheric pressure and temperatures from 30 to 90° C. The separation of esters from the reacted mixtures is carried out by distillation at low pressures. A process for esterifying sterols or stanols comprise forming a reacting mixture by contacting a lipase with a reactant mixture wherein the reactant mixture comprise sterols or stanols and one or more esters selected from the group consisting of esters of a fatty acid with a short chain aliphatic alcohol.

  • Patent number: 6462210
    Abstract: The present invention relates to a fractionation process of the unsaponifiable material derived from black-liquor soaps of the cellulose industry. Through this procedure fractions that essentially contain free sterols, fatty alcohols, sterol esters and fatty alcohol esters respectively are separated. Fractions containing sterols or fatty alcohols can be used as such in the alimentary, cosmetic and pharmaceutical industries or they can be used as raw materials for transforming into other useful products.

  • Patent number: 6297353
    Abstract: A method for obtaining neutral compounds from black-liquor soaps, tall oil and tall oil by-products is disclosed. The method includes the steps of: (1) dehydrating black liquor soaps, neutralized tall oil, or neutralized tall oil by-products to form a dehydrated current; (2) distilling the dehydrated current in a distillation column; (3) collecting an essentially soap free distillate; and (4) collecting an essentially neutral compound free residue. Also disclosed is a method for obtaining a sterol concentrate from black-liquor soap solutions, neutralized tall oil, or neutralized tall oil by-products. In this method, a distillation operation is repeated until a current of sterols with the desired purity is obtained. The method yields a sterol concentrate with a level of purity over 96%.
