Abstract
A process for the production of a magnesium chloride powder for use in a catalyst, the process comprising vaporizing magnesium chloride in a plasma torch and quenching the vapor with a liquid containing an electron donor to form a magnesium chloride-based powder catalyst wherein at least 80% by weight of the magnesium chloride is present as the hexagonal phase thereof. The invention also relates to a precursor for such a catalyst.
