    • The invention relates to a method for the distillative processing of a raw product containing cyclododecatriene obtained through the method of trimerization of butadiene, said method used for the extraction of the corresponding cyclododecatriene pure product. The distillative processing is carried out in either a dividing wall column in which a dividing wall is provided in the longitudinal direction of the column, forming an upper common column area, a lower common column area, a feed section with a reinforcing part and a down-thrust part and a withdrawal section with a down-thrust part and a reinforcing part, the raw product containing the cyclododecatriene being fed in the middle area of the feed section, a high-boiling fraction being drawn off from the column sump, a low-boiling fraction being drawn off of the column top and a mid-boiling fraction being drawn off of the middle area of the withdrawal section, or is carried out in thermally coupled columns.
    • 本发明涉及用于蒸馏后处理的含环十二碳三烯的粗制产物,将其通过程序获得丁二烯的三聚环十二碳三烯得到相应的纯产品的方法。 蒸馏是在每种情况下在分隔壁塔,其中在柱纵方向的分隔壁以形成上共同列区域,下公共列区域,供料区具有精馏段和汽提段,以及具有回收部和浓缩部撤回部分是,与在含有环十二碳三烯,粗产物供给 通过该柱的顶部,并从提取段,或在热耦合柱的中间区域的介质锅炉馏分从塔底执行的低沸点馏分的高沸点馏分的进料部分的中间区域,放电。
