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.
