US 11,691,934 B2 · Synthesis method and synthesis device for cyclododecene

Abstract

A synthesis method and a synthesis device of cyclododecene according to the present invention have a high conversion rate of cyclododecatriene which is a reactant and a high selectivity of cyclododecene which is a required product, and even so, have an effect of significantly decreasing a reaction time. In addition, the method and the device have an excellent conversion rate of cyclododecatriene and an excellent selectivity of cyclododecene, while maintaining excellent reactivity without an organic solvent such as ethanol. Therefore, a volume of the reactor relative to an output of cyclododecene may be further decreased. Moreover, the method and the device may minimize costs for facilities and process, are practical, decrease a process time, and are industrially advantageous for mass production as compared with the conventional art.
