Process to make small, discrete, spherical adducts

摘要

A process to make a small, discrete, spherical magnesium dihalide alcohol adduct is provided. This process comprises: contacting a magnesium dihalide and an alcohol in a high-viscosity liquid that consists of hydrocarbons, to obtain a dispersion; heating and agitating the dispersion to obtain a molten dipersion; cooling the molten dispersion to form said small, discrete, spherical magnesium dihalide alcohol adduct.
