专利号:US-5872245-A 优先权日:1992-09-30 标题 :Continuous process for the synthesis of sucrose fatty acid esters 发明人:WILSON DONALD C 权利人:OPTIMA TECHNOLOGIES GROUP 摘要:This present invention pertains to a process for the synthesis of sucrose fatty acid esters by reacting sucrose and a purified specific fatty acid ester under substantially solvent free conditions in the presence of a transesterification stationary catalyst and mechanical emulsification. The process is continuous, yielding selected individual products of separated simple sucrose fatty acid esters of mono-, di-, tri- and polyesters while recycling the unwanted ester fractions, the unreacted sucrose and fatty acid ester.
专利号:US-5034161-A 优先权日:1988-07-18 标题 :Synthesis of aryl-substituted aliphatic acids 发明人:ALINK BERNARDUS A O 权利人:PETROLITE CORP 摘要:A method for preparation of aryl-substituted aliphatic hydrocarbons is disclosed. The method comprises reacting in the presence of a solid superacid resin catalyst an unsaturated aliphatic hydrocarbon in liquid form with an aromatic hydrocarbon that is susceptible to Friedel-Crafts reaction. The reaction between the liquid unsaturated aliphatic hydrocarbon and the aromatic hydrocarbon produces a reaction product comprising an aryl-substituted aliphatic hydrocarbon.

The separated monounsaturated alkene compounds may be useful, for example, as a starting material in the synthesis of organic chemicals such as diacids, diesters, and the like.
专利号:WO-2008044544-A1 优先权日:2006-10-04 标题 :Fine particle of hydroxide and/or oxide and process for producing the same 发明人:HORIGUCHI SHINICHI; ARIZONO JYUNICHI; OOSHIMA YASUHIRO 权利人:NISSHIN SPINNING; HORIGUCHI SHINICHI; ARIZONO JYUNICHI; OOSHIMA YASUHIRO 摘要:Fine particles of a hydroxide and/or oxide which are produced by electrodialysis; and a process for producing the fine particles. A conductive liquid which is a poor solvent for the hydroxide and/or oxide to be generated in a synthesis chamber is used as a synthesis-chamber liquid. The synthesis chamber is used in combination with a desalting chamber separated from the synthesis chamber by a cation-exchange membrane, the desalting chamber being filled with an aqueous electrolyte solution containing metal ions as a raw material for the hydroxide and/or oxide. A voltage not lower than the theoretical water electrolysis voltage is applied to the chambers. The fine hydroxide and/or oxide particles, which are produced through electrodialysis, are reduced in equipment cost and production cost.

Its structure has been established by proton NMR spectrometry as being 16-hydroxy-9Z,12Z,14E-octadecatrienoic acid and closely related compounds, such as simple esters, amides, triglycerides, or other derivatives of the carboxylic acid function, and a method for its synthesis from linseed oil or methyl linolenate has been developed. The product from linseed oil, both in the form of the initially formed triglyceride and in the form of its free acid obtained by saponification, is useful for the treatment of sickle cell disease.
