    Abstract: 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.

    Abstract: The invention relates to a method for the trimerisation of butadiene to form cyclododecatriene by continuously feeding butadiene into a main reactor volume, for producing a reaction mixture in the main reactor volume which comprises non-converted butadiene and cyclododecatriene, and for providing isothermic conditions in the main reactor volume by tempering the reaction mixture. Said method also continuously the following steps: the reaction mixture produced in the main reactor volume is continuously guided into a post-reactor volume and converts at least one part of the non-converted butadiene in the post-reactor volume into cyclododecatriene. Said reaction mixture provided in the post reactor volume is essentially in adiabatic equilibrium. The invention also relates to a reactor arrangement for carrying out said method comprising a main reactor and a secondary reactor. Subsequently, in accordance with the inventive method, the temperature difference is detected for determining the butadiene concentration in the main reactor and for monitoring the operation or the method.

    Abstract: Process for recovering cyclododecatriene (CDT) from a solution containing CDT and high boilers such as deactivated catalyst and polymers, which includes feeding the solution into a preheater and heating it, subsequently depressurizing it through a downstream pressure maintenance device and feeding the resulting two-phase mixture into a helical tube evaporator and there reducing the CDT content of the liquid phase by partial evaporation and discharging a gaseous product stream having an increased concentration of CDT.
