Abstract
Cyclododecanone (CDON) is prepared by epoxidizing cyclododecene (CDEN) to epoxycyclododecane (CDAN epoxide), and rearranging the CDAN epoxide to CDON to obtain a mixture comprising said CDON and CDEN, wherein CDEN is separated from the CDON-containing mixture and sent to the epoxidation to CDAN epoxide in step a.
Claims16
