Alkoxy metal powder as well as preparation method and application thereof

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.

The state of Al(III) in alcohol solutions of aluminum alkoxide as probed by 27Al and 13C NMR and small-angle X-ray scattering

Solutions of aluminum alkoxides obtained by interaction of aluminum metal with methyl, ethyl, and isopropyl alcohols were studied by 27Al and 13C NMR and small-angle X-ray scattering. Alkoxides with a tetrahedral environment of aluminum prevail in methanol solutions, and those with an octahedral environment of aluminum predominate in ethanol solutions. In isopropyl alcohol at 293 K, polynuclear alkoxides with tetrahedral, octahedral, and pentacoordinated aluminum environments coexist. The structure of polynuclear complexes was refined by comparison of their calculated dimensions with small-angle X-ray scattering data.
