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 cyclododecane (CDAN), wherein CDAN is separated from the CDON-containing mixture and oxidized to CDON.
