Abstract
The present invention relates to a method of preparing cyclododecanone. According to the present invention, a method of preparing cyclododecanone which allows implementation of a high conversion rate and minimization of production of unreacted materials and reaction by-products may be provided. In addition, the present invention implements a high conversion rate and a high selectivity even by a simplified process configuration, and thus may be usefully utilized in an economical method of preparing laurolactam, allowing commercially easy mass production.
Claims13
A method of preparing cyclododecanone, the method comprising:
- applying heat while additionally injecting hydrogen peroxide to a mixture of cyclododecene and hydrogen peroxide under a catalyst system including a tungsten compound, a phosphoric acid compound, and an amine compound to prepare epoxidized cyclododecane;
- and preparing cyclododecanone by a rearrangement reaction without separation of a reaction mixture including the epoxidized cyclododecane under an alkaline metal halide catalyst.
