PROBLEM TO BE SOLVED: To provide a method for suppressing a by-product when producing cyclododecanone (CDON) by isomerizing epoxycyclododecane (ECD) in the presence of a catalyst. SOLUTION: When producing CDON by isomerizing ECD in the presence of an alkali metal halide, an alkali metal hydroxide, preferably in an amount of 1-5,000 ppm based on ECD weight is added to the isomerization reaction system.
