    • Efficient methods for the production of long-chain unsaturated dicarboxylic compounds are disclosed. Unsaturated dicarboxylic compounds may be prepared from a reaction mixture containing unsaturated carboxylic compounds in the presence of one or more catalysts. In addition to the unsaturated dicarboxylic compounds, alkene compounds may also be produced. The alkene compounds may be removed from the reaction mixture under reduced pressure. The method may also use a wiped-film still as a means to remove the alkene compounds from the reaction mixture. Reaction conditions may be monitored and/or controlled through the use of one or more electronic system(s) in communication with a variety of sensors and controllable devices.
    • 公开了生产长链不饱和二羧酸化合物的有效方法。 不饱和二羧酸化合物可以在一种或多种催化剂的存在下由含有不饱和羧酸化合物的反应混合物制备。 除了不饱和二羧酸化合物之外,还可以生产烯烃化合物。 可以在减压下从反应混合物中除去烯烃化合物。 该方法还可以使用擦拭膜作为从反应混合物中除去烯烃化合物的手段。 可以通过使用与各种传感器和可控设备通信的一个或多个电子系统来监视和/或控制反应条件。

    • The present invention provides a chromatographic separation process for recovering a polyunsaturated fatty acid (PUFA) product, from a feed mixture, which process comprises introducing the feed mixture to a simulated or actual moving bed chromatography apparatus having a plurality of linked chromatography columns containing, as eluent, an aqueous alcohol, wherein the apparatus has a plurality of zones comprising at least a first zone and second zone, each zone having an extract stream and a raffinate stream from which liquid can be collected from said plurality of linked chromatography columns, and wherein (a) a raffinate stream containing the PUFA product together with more polar components is collected from a column in the first zone and introduced to a nonadjacent column in the second zone, and/or (b) an extract stream containing the PUFA product together with less polar components is collected from a column in the second zone and introduced to a nonadjacent column in the first zone, said PUFA product being separated from different components of the feed mixture in each zone.
    • 本发明提供了一种用于从进料混合物中回收多不饱和脂肪酸(PUFA)产物的色谱分离方法,该方法包括将进料混合物引入到具有多个连接色谱柱的模拟或实际移动床层析装置中, 洗脱液,含水醇,其中所述装置具有包括至少第一区和第二区的多个区,每个区具有提取物流和可从所述多个连接的色谱柱从其中收集液体的萃余液流,并且其中 (a)从第一区域的塔中收集含有PUFA产物和更极性组分的萃余液流,并将其引入第二区域中的不相邻的塔,和/或(b)含有PUFA产物的萃取物流与 从第二区域中的塔收集较少的极性组分,并将其引入第一区域中的不相邻的塔 ,所述PUFA产物在每个区域中与进料混合物的不同组分分离。
