  • Patent number: 7932409
    Abstract: A process for producing oleochemical polyols comprises the steps of epoxidizing unsaturated oil using an organic acid together with oxygenated water or a per-acid to obtain epoxidized oil; washing the epoxidized oil with salt water to remove unused organic acid together with oxygenated water or a per-acid; neutralizing acidic condition of the washed epoxidized oil with a base; washing the neutralized epoxidized oil with a salt solution until the pH of the neutralized epoxidized oil reaching 6.5 to 7.5 to removed the base residue; drying the washed neutralized epoxidized oil under vacuum; and reacting the washed neutralized dried epoxidized oil with polyhydric alcohol in the presence of boron trifluoride-diethylether complex to produce the oleochemical polyols. The oleochemical polyols are then subjected to the same washing, neutralizing, washing and drying process as in preparing the washed neutralized dried epoxidized oil.

  • Patent number: 7629478
    Abstract: A process for preparing palm-based polyol monomer includes reacting unsaturated fatty acids or its corresponding triglycerides with polyhydric alcohol. In particular, one example uses oleic acid with about 70% purity as the starting material for preparing the polyol monomer. Moreover, another example uses refined, bleached, and deodorized (RBD) palm olein as an alternative to oleic acid as the starting material. The preparation of the polyol monomer involves the production of monoglyceride of unsaturated fatty acids, which was further epoxidized with peracid and finally ring opened with polyhydric alcohols. Such polyol monomer is used as a raw material for the production of various types of polyurethane products.

  • Patent number: 7560578
    Abstract: The present invention relates to an improved process for producing hydroxy fatty acids preferably dihydroxy or polyhydroxy acids from unsaturated fatty acids derived from natural oils and fats. The unsaturated fatty acids extracted from natural vegetable oils or animal fats preferably palm-based oleic acid is hydroxylated or oxidized by peracetic acid which formed in situ from a mixture of hydrogen peroxide and formic acid. The process for producing dihydroxy or polyhydroxy fatty acids according to the present invention involve less cost, easier to perform and reduced reaction time.

  • Patent number: 7098351
    Abstract: This invention discloses a rapid method of production for fatty acid amide from fatty acid and urea. One example is the preparation of oleylamide from oleic acid and urea. The yields are high and oleylamide is selectively formed by judicious choice of catalyst. The production of fatty acid amide involves heating fatty acid and urea in a microwave oven with the use of Lewis acid catalyst. The product from the reaction is subjected to solvent extraction with chloroform and then followed by purification with n-hexane, ethanol and acetonitrile via recrystalization method. Such an oleylamide is preferred for application as a mould release agent, slip agent in plastic film production, water repellent and as a raw material for cosmetics production.
