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.

A plant leaves-derived carbon material doped with two metals and preparation and use thereof are provided, the carbon material prepared by carbonizing, in an inert atmosphere, plant leaves which have absorbed ions of two metals M1 and M2. The metal M1 is Co, Mn, or Fe. The metal M2 is Ni, Cu, or Zn. The carbon material can be used as an efficient, green, and safe catalyst for the selective oxidation of cycloalkanes to produce cycloalkanols and cycloalkanones, and enable an increased selectivity of the target products (thus less by-products), a low yield of cycloalkyl peroxides, reduced reaction temperature, low environmental impact, and safe production.

The invention relates to a method for producing cyclododecanone (CDON). During the production, contaminated cyclododecane (CDAN) is produced. This can be separated from CDON by distillation (CDAN-containing fraction). The separation of CDAN and impurities such as 13-oxabicyclo [7.3.1]tridecane occurs by crystallizing out CDAN from the CDAN-containing fraction.
