摘要:The present disclosure provides a preparation method of resveratrol nervonic acid ester, comprising the following steps of: step 1: weighing resveratrol, a nervonic acid and thiocarbonyldiimidazole according to a molar ratio of 1:1:0.8 to 1:7:11.2 in a reactor; step 2: adding a certain amount of solvent into the reactor to completely dissolve the reactants; and step 3: stirring for reaction at room temperature for 30 min to 180 min. The preparation method is safe, efficient and clean, and enables synthesis of the resveratrol nervonic acid ester with high conversion rate, high purity and high yield.

摘要:Processes for the enzyme-catalyzed synthesis of triglycerides containing polyunsaturated fatty acids in which the synthesis is preceded by a pre-hydrolysis in which (a) C 1-4 alkyl esters of polyunsaturated fatty acids are completely or partly hydrolyzed in vacuo with continuous addition of water or are partly hydrolyzed in several stages without vacuum, (b) after the hydrolysis, the water is removed by separation or distillation and (c) the synthesis of the polyunsaturated fatty acids with glycerol in vacuo in the presence of an enzyme to form their triglycerides is carried out under low-water conditions, (d) the enzymes are removed from the triglyceride by separation or filtration and (e) the remaining fatty acids and/or possible residues of C 1-4 alkyl esters are removed from the triglyceride by distillation or refining; the pre-hydrolysis and the subsequent synthesis preferably being carried out as a one-pot process in the same reactor and in the presence of the same enzyme.

标 题:Synthesis of conjugated linoleic acid (CLA)
发明人：SEIDEL MICHAEL C
摘要:A synthesis process for producing 9-cis, 11-trans octadecadienoic acid at room temperature in high yield is disclosed, including providing a tosylate or mesylate of a methyl ester of ricinoleic acid and 9-cis, 11-trans octadecadienoic acid formed when the tosylate or mesylate reacts with diazabicyclo-undecene. In one aspect, the tosylate of the methyl ester of ricinoleic acid is formed with tosyl chloride in a pyridine solvent. In one aspect, the mesylate of the methyl ester of ricinoleic acid is formed with mesyl chloride in acetonitrile and triethyl amine. In one aspect, the tosylate or mesylate is reacted with diazabicyclo-undecene in a polar, non-hydoxylic solvent of acetonitrile to form the preferred isomer of 9-cis, 11-trans octadecadienoic acid at room temperature in high yield.

摘要:Methods of producing concentrates of omega-3 fatty acid ethyl esters, from an ethyl ester composition comprising use of free fatty acids as co-catalysts for enzymatic synthesis of partial glycerides are provided. In some embodiments, methods of producing concentrates of ethyl-eicosapentanoate and/or ethyl-docosahexanoate from an ethyl ester composition containing the esters comprise a) adding glycerol, an immobilized enzyme catalyst, and a free fatty acid co-catalyst b) allow glyceryl ester synthesis to proceed by adjustment of temperatures, time and vacuum such that a substantial amount of partial glycerides is formed and c) separating an ethyl ester fraction enriched in ethyl eicosanoate and ethyl docosahexanoate from the glyceride mixture.

标 题 :Silver ion chromatography of high purity conjugated linoleic acid (CLA)
发明人：SEIDEL MICHAEL C
摘要:A method for providing a purified conjugated linoleic acid (CLA) is disclosed. The purified conjugated linoleic acid (CLA) is formed by separating by liquid chromatography a 9-cis, 11-trans octadecadienoic acid formed by a novel synthesis of reacting an ester of ricinoleic acid with a tosyl chloride or a mesyl chloride to form a tosylate or mesylate of an ester of ricinoleic acid, and reacting the tosylate or mesylate of an ester of ricinoleic acid with diazabicyclo-undecene. Reacting an ester of ricinoleic acid with a tosyl chloride or a mesyl chloride to form a tosylate or mesylate of an ester of ricinoleic acid, and reacting the tosylate or mesylate of an ester of ricinoleic acid with diazabicyclo-undecene forms a 9-cis, 11-trans octadecadienoic acid having a purity greater than 50%, and separating by liquid chromatography forms a 9-cis, 11-trans octadecadienoic acid having a purity greater than 90%. In one aspect, the liquid chromatography uses a strong acid macroreticular ion exchange resin. In one aspect, the liquid chromatography includes silver ion liquid chromatography.
