Definitions
- the present invention relates to a method for synthesizing a magnesium dialkoxide granular material used for a solid catalyst component for olefin polymerization.
- Magnesium diethoxide is used as a solid catalyst component for the polymerization of olefins such as propylene. Since the shape of polypropylene obtained by polymerization is similar to the shape of the polymerization catalyst, generally used magnesium diethoxide is spherical or elliptical, and is in a practical stage in consideration of the strength of the polymerization catalyst. Is used in which the average particle size represented by D 50 is several tens of ⁇ m, usually 60 ⁇ m or less.
- a method of synthesizing spherical or elliptical magnesium diethoxide by direct reaction of magnesium metal and ethyl alcohol has long been known from Patent Document 1 and the like, but this method can synthesize a product with a large bulk density. Difficult, those with a large average particle size are insufficient in strength, and when used as a solid catalyst component for polymerization of olefins, pulverization and pulverization occur in the preparation process, resulting in poor catalyst yield, Since the catalyst is also expensive, low-priced magnesium chloride or the like is widely used as a solid catalyst component for polymerization of olefins despite its excellent polymerization activity. Also, the strength of the obtained catalyst itself tends to be insufficient, and problems are likely to occur particularly when used in a fluidized bed.
- Patent Document 2 describes a mixed magnesium dialkoxide which is a mixture of a metal magnesium dialethoxide and another dialkoxide, but does not describe the bulk density of the mixed magnesium dialkoxide.
- the present invention directly causes solid-liquid reaction between granular metal magnesium having an average particle size of 50 ⁇ m to 500 ⁇ m and two or more alcohols composed of at least one of ethyl alcohol and an alcohol having 3 to 6 carbon atoms.
- granular metal magnesium having an average particle size of 50 ⁇ m to 500 ⁇ m and two or more alcohols composed of at least one of ethyl alcohol and an alcohol having 3 to 6 carbon atoms.

- alcohols used with ethyl alcohol include n-propyl alcohol, isopropyl alcohol, n-butyl alcohol, isobutyl alcohol, t-butyl alcohol, pentanol, cyclohexyl alcohol, and phenol. It is not limited to. In particular, isopropyl alcohol and n-propyl alcohol are preferable. Since methyl alcohol decreases the polymerization activity of the polymerization catalyst for olefins using the obtained mixed magnesium alkoxide, it is not preferable to use it as a reactant or a solvent.
- the molar ratio of ethyl alcohol to other alcohols is preferably 97 to 85: 3 to 15 (total 100), and especially 97 to 87: 3 to 13 (total 100) of mixed alcohols.
- the proportion of other alcohol used is less than 3 mol%, the content of alkoxide other than diethoxide in the mixed magnesium dialkoxide does not reach 2.5 mol%, and the bulk density of the product in that case is 0.4 g / Can not be more than ml.
- the proportion of other alcohol used exceeds 15 mol%, it becomes difficult to aggregate the product into granular materials, and a bulk density of 0.4 g / ml or more cannot be obtained.
- ethyl alcohol and isopropyl alcohol or n-propyl alcohol are particularly preferable to use ethyl alcohol and isopropyl alcohol or n-propyl alcohol as the two kinds of alcohol.
- the magnesium dialkoxide produced when these two types of alcohols are used is composed of a mixture of magnesium diethoxide and magnesium dipropoxide, and the production rate is almost proportional to the proportion of the mixed alcohol used.
- the average particle diameter of the metallic magnesium is preferably 50 ⁇ m to 500 ⁇ m, particularly preferably 100 to 250 ⁇ m.
- Two or more kinds of alcohols composed of this granular metallic magnesium and other aliphatic alcohols such as ethyl alcohol and isopropyl alcohol are mixed with ethyl alcohol.
- the content of n-proposide or isopropoxide in the entire alkoxide is 2.5 to 13.0 mol%, and the average particle size represented by D 50 is 20 to 80 ⁇ m.
- the mixed magnesium dialkoxide granular material thus obtained is used as a solid catalyst component, using a tetravalent titanium compound such as titanium tetrachloride and an electron donating compound (donor) such as dibutyl phthalate or cyclohexylmethyldimethoxysilane.
- a polymerization catalyst for polyolefin can be produced.
- An organoaluminum compound such as triethylaluminum is used for these, and the olefin is polymerized from the olefin gas by slurry polymerization.
- a magnesium dialkoxide having high strength can be obtained by using a mixed alcohol. Therefore, when used for an olefin polymerization catalyst, there is little destruction in the preparation process, and the catalyst acquisition yield is increased. I can do it.
- the polymerization activity of the catalyst is improved by about 25% compared with the conventional product, and the yield of the resulting polyolefin can be increased by 25%.
- the strength of the obtained polymerization catalyst is greater than that of the conventional magnesium diethoxide used alone, the collapse of the catalyst during preparation of the conventional method is prevented in polyolefins and the like, resulting in an increase in the yield of polyolefin and the resulting polyolefin. This helps prevent particle shape collapse. Further, there is little catalyst loss when using the fluidized bed polymerization method, and trouble can be reduced.
- the average particle diameter of the metal magnesium used is particularly preferably 100 to 250 ⁇ m, and the molar ratio of ethyl alcohol to 97 to 85% by weight ratio of the granular metal magnesium to ethyl alcohol and isopropyl alcohol
- molar ratio 1/3 to 30 and directly reacting under reflux of the alcohol.
- an average particle size of 10 ⁇ 80 [mu] m indicated by D 50, preferably 20 to indicate the range of particle shape of 80 [mu] m bulk density can be preferably synthesized mixed magnesium dialkoxide granules above 0.4 g / ml.
- the bulk density of the mixed magnesium dialkoxide granule is 0.4 or more, preferably 0.41 or more, more preferably 0.42 or more, and preferably 0.6 or less, more preferably 0. .5 or less.
- the mixed magnesium dialkoxide granular material having a large bulk density has an effect that the pulverization loss when producing an olefin polymerization drunk catalyst using this is small, and thus the catalyst acquisition yield is high.
- the strength of the resulting polymerization-induced catalyst is high, it is expected that it can be advantageously used for gas phase polymerization of olefins.
- D 50 used here a particle size distribution of the granules were measured, the integrated value of the particle weight is intended to refer to a particle size ([mu] m) when a 50% by weight, whole numbers granules This indicates an intermediate value of the particle size.
- D 10 and D 90 indicate the particle sizes when the integrated values are 10% and 90%, respectively.
- the metal magnesium used in the present invention it is optimal that the average particle size of D 50 is 50 to 500 ⁇ m, and that the particle size distribution represented by (D 90 -D 10 ) / D 50 is 2 or less.
- Various types of metal shapes such as powder and cutting are used, but the metal particles are kept in an inert gas (such as nitrogen) atmosphere with minimal oxidation of the metal particle surface, A material that has been treated with a solvent that does not affect the reaction on the metal surface to prevent oxidation of the particle surface is suitable.
- the alcohol used together with ethyl alcohol in the present invention may have an alkyl group having 3 to 6 carbon atoms, a cycloalkyl group or an aromatic alkyl group, preferably an aliphatic alcohol having 3 to 6 carbon atoms, particularly n-Propyl alcohol, more preferably an aliphatic branched alcohol having 3 to 6 carbon atoms, particularly isopropyl alcohol.
- the reaction between magnesium metal and two kinds of alcohols may be started by adding a mixed liquid in which two kinds of alcohols are mixed in a predetermined ratio to a reaction system in which metal magnesium is present from the beginning. Only alcohol may be added to the reaction system, and two kinds of mixed alcohols may be added after the start of the reaction due to heat generation or hydrogen generation is confirmed.
- the total amount of the two alcohols used relative to the magnesium metal is 3/1 to 30/1 by weight.
- the amount of the two alcohols is less than 3 times the amount of magnesium, the smooth reaction does not proceed, and the residual metal magnesium unreacted substance and the particle size cannot be controlled.
- the ratio exceeds 30 times, a lot of alcohol is contained in the particles formed by the reaction, and when the alcohol is distilled off during drying, a lot of voids are generated in the particles, and particles with low bulk density are made. Not suitable for.
- the mixed magnesium dialkoxide granular material of the present invention is composed of a porous material in which primary particles of a mixed magnesium dialkoxide having a particle diameter of 1 to 10 ⁇ m in the form of a sphere, ellipse, scale or needle are aggregated.
- a catalyst In the synthesis reaction of the magnesium dialkoxide of the present invention, it is preferable to use a catalyst.
- the catalyst alkyl halide, metal halide, iodine and the like are used.
- the amount used is 0.1 to 20.0% by mass, preferably 0.5 to 10.0% by mass, based on the magnesium metal.
