Reaction Steps

Further, Zh. Org. Khim (1990), 26(7), 1497-1500, discloses that, when an isomerization reaction of an epoxycyclododecane was carried out in the presence of 2.3 molar % of a catalyst consisting of LiBr (lithium bromide) at a reaction temperature of 150° C. for a reaction time of 10 hours, the target cyclododecanone was obtained at a yield of 96.6%, and when the reaction of the epoxycyclododecane was effected in the presence of 1.5 molar % of LiI (lithium iodide) at 150° C. for 5 hours, the target cyclododecanone was obtained at a yield of 91.2%. In the case of this report, however, it is assumed that, to make the conversion of the epoxycyclododecane close to 100%, a very long reaction time is necessary. Also, the reaction of the report was effected in a batch-type reaction system, and thus no continuous method for the reaction is disclosed in the report.
