Embodiment 1

[0068] In a reactor fully replaced with nitrogen, add 30 g of calcium dichloride and 100 mL of hexane at 25°C, stir for 0.5 hours, add 25 g of sodium ethoxide, stir, and the reaction temperature rises to 60°C, and react for 6 hours. Stop the reaction, lower the temperature to 30°C, filter, wash with hexane three times, and vacuum-dry at 50°C for 1 hour to obtain 33 g of calcium ethoxide powder, BD=0.39.

Embodiment 2

[0070] In the reactor fully replaced by nitrogen, add 45g of magnesium dichloride and 50mL of hexane at 5°C, stir for 1 hour, add 20g of sodium ethoxide, stir, the reaction temperature rises to 80°C, and react for 10 hours. Stop the reaction, lower the temperature to 25°C, filter, wash with hexane four times, and dry in vacuum at 40°C for 2 hours to obtain 48 grams of magnesium ethoxide powder, BD=0.40.

Embodiment 3

[0072] In a reactor fully replaced by nitrogen, add 40 g of aluminum trichloride and 80 mL of heptane at 35°C, stir for 6 hours, add 41 g of potassium ethoxide, stir, the reaction temperature rises to 120°C, and react for 35 hours. Stop the reaction, lower the temperature to 20°C, filter, wash with hexane four times, and vacuum-dry at 60°C for 1 hour to obtain 42 grams of aluminum ethoxide powder, BD=0.39.

Abstract

The invention relates to a preparation method and an application of alkoxy metal powder, which are applied to preparation of an alkoxy metal carrier of an olefin polymerization catalyst. The alkoxy metal carrier comprises the following components: metal halide, sodium alcoholate or potassium alcoholate, or a solvent. The molar ratio of the components for preparing the alkoxy metal compound is as follows: metal halide: sodium alcoholate or potassium alcoholate = 1:(0.001-30); wherein the metal halide is a metal chloride, a metal bromide, a metal fluoride or a metal iodide; the metal is a main group metal, a sub-group metal or a VIII group metal. The catalyst prepared from the carrier is used for preparing an olefin polymerization catalyst, and has the advantages of high catalyst activity, good hydrogen regulation performance, good copolymerization performance, low polymer powder content, low wax content and good particle morphology; the catalyst is used for ethylene homopolymerization,ethylene and alpha-olefin copolymerization or ethylene and polar alkene monomer copolymerization, propylene homopolymerization, propylene and alpha-olefin copolymerization, or propylene and polar alkene monomer copolymerization.
