ALCOHOL ADDUCT OF MAGNESIUM HALIDE, ITS OBTAINMENT AND APPLICATION

摘要

FIELD: chemistry. ^ SUBSTANCE: invention concerns method of obtaining alcohol adduct particles of magnesium halide and their application in production of olefin polymerisation catalysts. The claimed method involves: (1) magnesium halide contact to alcohol in inert liquid medium for obtaining alcohol adduct melt of magnesium halide; (2) dispersion of inert liquid medium mix with alcohol adduct melt of magnesium halide obtained at stage (1), by rotation in high gravitation field to obtain dispersed alcohol adduct melt of magnesium halide; dispersion is performed in high-gravitation rotation mill-type reactor at rotation rate of 100 to 3000 rpm, high-gravitation rotation mill-type reactor is packed with Sultzer filler with average pore size of 0.1 to 8 mm, porosity of 90 to 99 percent, specific surface area of 100 to 3000 m2/m3 and wire diametre of 0.05 to 0.5 mm; and (3) cooling of melt dispersion obtained at stage (2), to form alcohol adduct particles of magnesium halide. ^ EFFECT: simple and easy method of obtaining alcohol adduct particles of magnesium halide with narrow spread of particle size. ^ 12 cl, 1 tbl, 1 dwg, 9 ex
