An Improved and Suitable Method for Large Scale Production ofα-Monochlorocyclodecanone

: α-Monochlorocyclododecanone was synthesized from cyclododecane and 1,3-Dichloro-5,5-dimethylhydantoin (DCDMH) catalyzed with silica gel in MeOH. The product was obtained by crystallization with nearly 85% yield. The presented method used cheap raw materials, mild reaction conditions, simple separation method and environment-friendly process. Additionally, the current synthesis provided an ideal approach for large-scale production.
