专利号:US-5637757-A 优先权日:1995-04-11 标 题 :One-pot synthesis of ring-brominated benzoate compounds 发明人:HILL JOHN E; FAVSTRITSKY NICOLAI A; MAMUZIC RASTKO I; BHATTACHARYA BHABATOSH 权利人:GREAT LAKES CHEMICAL CORP 摘要:A method of preparing tetrabromobenzoate compounds from tetrabromophthalic anhydride by reacting tetrabromophthalic anhydride with alcohol in the presence of a decarboxylation catalyst. The reaction may be carried out in an excess of alcohol, or with a near stoichiometric amount of alcohol by performing the reaction in an inert solvent.
专利号:WO-2009115221-A1 优先权日:2008-03-18 标题:Composition for low colour of unsaturated glycidyl esters derivatives and the use thereof 发明人:HEYMANS DENIS MARIE CHARLES; UYTTERHOEVEN GRIET 权利人:HEXION SPECIALTY CHEMICALS RES; HEXION SPECIALTY CHEMICALS INC; HEYMANS DENIS MARIE CHARLES; UYTTERHOEVEN GRIET 摘要:The present invention relates to a composition comprising an aliphatic branched alcohol and glycidyl functional product esters, which are currently used in the synthesis of radical polymerisable acrylic or methacrylic acid derivatives, to be further reacted into resins for coating applications. Another aspect of the present invention is formed by the cured coating films derived from the hereinbefore defined coating compositions and applied on a shaped substrate, and more in particular on automotives.
专利号:US-10017465-B2 优先权日:2014-08-12 标 题 :Method for producing astaxanthin from astacin 发明人:Schäfer Bernd; SIEGEL WOLFGANG 权利人:BASF SE 摘要:The invention relates to a method for the non-stereoselective and also for the stereoselective synthesis of astaxanthin from astacin. For this purpose, a reducing agent is used selected from the group of hydrogen, a secondary alcohol, formic acid and also the salts of formic acid or from a mixture of at least two representatives of the compound classes stated above. The invention further relates to the use of astacin as starting compound for the synthesis of astaxanthin.
