1-butene is a highly important sought after commodity mainly as a co-monomer for polymer production. Several processes to generate this compound are commercially available. One of them is the selective dimerization of ethene via a Ziegler-Natta type oligomerization catalyst system. The commercial process is around for more than 25 years. The current system generates butenes selectively exceeding 90+% purity of which 1-butene exceeds 98+%. Due to the expected significant market growth, new interest in this system has been rekindled. The presentation shows newest results tackling the problems of the 'old' system and improvements to a new catalyst and process generation.
