20080200706 | Conjugated Linoleic Acid Compositions - Novel compositions containing conjugated linoleic acids are efficacious as animal feed additives and human dietary supplements. Linoleic acid is converted to its conjugated forms in which the resulting composition is low in certain unusual isomers compared to conventional conjugated linoleic products. In addition, the inventions provides compositions that are prepared according to a novel method that controls oxidation of CLA into volatile organic compounds as well as containing metal oxidant chelators to control oxidation during storage. | 08-21-2008 |
20090137829 | Methods for Preparation and Use of Strong Base Catalysts - Methods for preparation of a unique superbase catalyst consisting of mixture of polyether alcohol and base in which a polyether alcohol superbase is produced by the removal of water or alcohol at elevated temperatures to form a polyether alcohol alkoxide. The superbase catalyst is useful in, but not limited to, quantitative isomerization of alkyl esters of vegetable oils containing interrupted double bond systems to yield esters with conjugated double bond systems, alkylations, arylations, acylations, aminations, condensations, eliminations, isomerizations, rearrangements, and Wittig reactions. | 05-28-2009 |
20110295027 | Catalytic Isomerisation of Fatty Acid Esters - Catalytic isomerisation of fatty acid esters to form branched fatty acid esters comprises the steps of contacting a feedstock having at least one fatty acid ester with a catalyst and isolating from other reaction products branched fatty acid esters that are produced. The catalyst is a crystalline porous silicoaluminophosphate catalyst having silicon, aluminum, and phosphorous atoms in lattice framework positions. The branched fatty acid esters formed thereby demonstrate properties suitable for use in various applications. | 12-01-2011 |
20110301371 | PROCESS - A process for producing a conjugated di- or poly-unsaturated fatty acid having from 12 to 24 carbon atoms, or a salt or ester thereof, comprises: reacting a non-conjugated free fatty acid, or a salt or ester thereof, with a base in the presence of an alcoholic solvent comprising ethanol; and separating the conjugated fatty acid from the reaction mixture, wherein the separation of the conjugated fatty acid from the reaction mixture comprises contacting the reaction mixture with an aqueous salt solution and removing a liquid phase which comprises the salt solution and at least a part of the solvent from a solid phase which comprises a salt of the conjugated fatty acid. | 12-08-2011 |
20120071676 | SYNTHESIS OF TERMINAL ALKENES FROM INTERNAL ALKENES AND ETHYLENE VIA OLEFIN METATHESIS - This invention relates generally to olefin metathesis, and more particularly relates to the synthesis of terminal alkenes from internal alkenes using a cross-metathesis reaction catalyzed by a selected olefin metathesis catalyst. In one embodiment of the invention, for example, a method is provided for synthesizing a terminal olefin, the method comprising contacting an olefinic substrate comprised of at least one internal olefin with ethylene, in the presence of a metathesis catalyst, wherein the catalyst is present in an amount that is less than about 1000 ppm relative to the olefinic substrate, and wherein the metathesis catalyst has the structure of formula (II) | 03-22-2012 |
20130245299 | Method For The Production Of Conjugated Polyunsaturated Fatty Acids With Heterogenous Catalysts - The present invention relates to an improved process for the production of conjugated polyunsaturated fatty acids (PUFA), preferably conjugated linoleic acid (CLA), using finely dispersed heterogeneous metal catalysts on a mesoporous support, in the absence of Hg. The present invention also relates to a method to increase the large microporosity and (optionally) the small mesoporosity of a zeolite, thus obtaining a modified zeolite having a large and highly accessible internal surface. | 09-19-2013 |
20160039737 | USE OF SOLUBLE METAL SALTS IN METATHESIS REACTIONS - The present invention describes the use of soluble metal salts to reduce impurities and metathesis catalysts poisons from olefinic feedstocks to improve olefin metathesis efficiency. The soluble metal salts were added to the olefinic feedstocks to prevent peroxides and catalyst poisons from inhibiting the metathesis catalyst. The soluble metal salts remain in the olefinic feedstocks and are used without further purification in the olefin metathesis reactions. The key to this invention is the soluble metal salt compounds do not inhibit the olefin metathesis catalysts but unexpectedly increase olefin metathesis catalyst efficiency while prior art heterogeneous metal complexes sequester the olefin metathesis catalyst, preventing olefin metathesis. | 02-11-2016 |
20160160154 | CONJUGATED LINOLEIC ACID RICH VEGETABLE OIL PRODUCTION USING HETEROGENEOUS CATALYSIS - The invention is directed to CLA-rich vegetable oil production from linoleic rich oils by heterogeneous catalysis. The process produces conjugated PUFA in triglyceride form, preferably at least 20% CLA-rich, by isomerization of a non-conjugated PUFA in vegetable oils using a heterogeneous transition metal catalyst promoted by an organic acid and/or thiol-containing compound. The heterogeneous catalysis isomerization process can use steam/vacuum distillation, hydrogenation unit and/or deodorization to produce CLA-rich soy oil. After processing, any catalyst residue may be removed by filtration, beaching, deodorizing, adsorbents or centrifugation to obtain high quality, CLA-rich oils. | 06-09-2016 |
