실험 절차
The starting cyclododecanone material usable for the process of the present invention can be prepared by oxidizing cyclododecane with a molecular oxygen-containing gas or by isomerizing epoxycyclododecane. In the oxidation method, cyclododecane is oxidized with oxygen gas or a molecular oxygen-containing gas in the presence of a boron compound to provide a reaction product mixture comprising cyclododecanol and cyclododecanone, the reaction product mixture is hydrolysed, the boron compound is removed from the hydrolysis product mixture, non-reacted cyclododecane is separated and recovered from the hydrolysis product mixture by distillation, and a mixture of cyclododecanol with cyclododecanone is collected from the residual fraction. The mixture is subjected to a dehydrogenation procedure to convert cyclododecanol to cyclododecanone. In this dehydrogenation procedure, a portion of the resultant cyclododecanone is occasionally further dehydrogenated to produce cyclododecenone.
