Paragraph 0099-0100, (2019/12/02)
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 authors have carried out an investigation aimed at development of more convenient methods for production of alkyl orthotitanates in two-phase systems. In studies of the reaction of titanium tetrachloride with alcohols in presence of organic amides the authors found that the latter are not indifferent solvents but take part in the reaction. The interaction of titanium tetrachloride, an organic amide, and an alcohol in 1:4:(8-9. 6) molar ratio results in splitting of the amide and formation of the corresponding amine hydrochloride and ester.
