Abstract

The present invention relates to cyclododecanone and a preparation method therefor. According to the present invention, a cyclododecanone preparation method capable of achieving a high conversion rate and minimizing unreacted materials and the production of reaction byproducts can be provided. In addition, the present invention implements a high conversion rate and selectivity despite a simplified process, and thus can be helpfully utilized in economical laurolactam production methods that are easy to mass-produce commercially. According to the present invention, the proportions of cyclododecanol, cyclododecadiol, and the like, obtained as reaction byproducts, in the final product can be drastically reduced, and cyclododecanone can be produced at a high conversion rate.
