    摘要: A process for removing a cyclododecanone-rich fraction from a dehydrogenation mixture containing low boilers, cyclododecanone, medium boilers, cyclododecanol and high boilers is provided. According to the process, the cyclododecanone is separated from the cyclododecanol in a dividing wall column. The apparatus which is the dividing wall column is also provided within this invention.

    摘要: A process for removing a cyclododecanone-rich target fraction (A) from a dehydrogenation mixture (O) comprising low boilers (LB), cyclododecanone (CDON), medium boilers (MB), cyclododecanol (CDOL) and high boilers (HB) is provided. According to the process, substantially pure CDON is obtained via a distillative sequence of two side draw columns connected in series, wherein the sidestream of the primary side draw column is fed into the secondary side draw column. From the top of each of the two side draw columns, a CDON-rich fraction is drawn off, and these are combined to form a target fraction, which is essentially pure CDON.
