The present invention provides a continuous preparation method of cyclododecatriene including: preparing a reaction composition by mixing butadiene, a main catalyst, and a co-catalyst with a toluene solvent; and allowing the reaction composition to react at a reaction pressure higher than a vapor pressure of the butadiene, and a cyclododecatriene composition prepared by the continuous preparation method.

1,5,9-cyclododecatriene composition and continuous preparation method therefor

The present invention relates to a laurolactam preparation method and synthesis apparatus, and epoxidation and a rearrangement reaction are performed in the conversion of cyclododecene into cyclododecanone so that the preparation method can synthesize laurolactam having a higher purity with a higher selectivity and in a higher yield than a conventional preparation method.
