Process for production of MgCl2, MgO with small particle size distribution and its use as catalyst support for the polymerisation of olefins.

摘要

Process for the manufacture of (MgCl2.MgO) of narrow particle size distribution by treatment of hydrated MgCl2 with an alcohol followed by a heat treatment after partial removal of the alcohol, characterised in that the hydrated MgCl2 is suspended in the alcohol, the alcohol to hydrated MgCl2 molar ratio being less than the solubility ratio of these two bodies at the temperature of the suspension. The MgCl2.MgO obtained can be used as a support in the catalytic components for the polymerisation of olefins.
