Abstract:
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.
