Abstract
The invention relates to a homogeneous catalyst for the production of linear alpha-olefins by oligomerisation of ethylene, consisting of a zirconium salt of organic acids and a cocatalyst which consists of alkylaluminiums and/or aluminium chloride. The activity of the catalyst, system may sometimes be raised substantially by adjusting the molar ratio of chlorine to aluminium in the cocatalyst within the range between 1.0 and 1.5. The economic viability of the production process and product purity are improved.
