Abstract:
Preparation of cyclododecatriene in a continuous or discontinuous process by trimerization of butadiene in the presence of a catalyst system and a solvent, the crude cyclododecatriene obtained being able to be isolated by means of distillation. The cyclooctadiene formed as by-product can likewise be isolated from the crude product.
