Description
Technical field
The present invention relates to a kind of preparation method of the alkoxyl magnesium carrier for olefin polymerization catalysis.
Background technology
At present, one of most widely used olefin polymerization catalysis is catalyzed by the Ziegler-Natta of magnesium chloride carrying
Agent.The Ziegler-Natta catalyst of magnesium chloride carrying is typically to be made up of the organic compound of magnesium, titanium, halogen and supplied for electronic
Ingredient of solid catalyst.When in polymerization of Alpha-olefin, such as propylene in use, it can be with organic calorize as co-catalyst
Compound and organic silane compound as stereospecificity conditioning agent are mixed and used in proper proportions.Due to for alkene
The solid catalyst of the carrying of polymerized hydrocarbon is in various commercial polymerization techniques, such as slurry polymerization, polymerisation in bulk, gas-phase polymerization etc.
Middle use, therefore they need to meet various requirements on particle shape, for example, it is suitable particle size and shape, uniform
Size distribution, the bulky grain of minimum or particulate and high bulk density etc., and the performance of basic demand, such as high catalysis
Agent activity and stereospecificity.But not a kind of catalyst disclosure satisfy that various demands, and using alkoxyl magnesium as carrier
Loaded catalyst can have more premium properties.As Application No. CN200580028649.3,
Multiple patents such as CN200580032074.2 and 01137496.9 are all mentioned with alkoxyl magnesium is carrier to improve the more of catalyst
Kind performance.It is therefore desirable to the manufacturing technology for the alkoxyl magnesium for developing premium properties.
The preparation method of published spherical dialkoxy magnesium mainly has following several：First, alcohol and magnesium metal first react raw
Into dialkoxy magnesium, particle size is then adjusted by mechanical crushing；2nd, magnesium metal and during ethanol synthesis, magnesium and ethanol
Final ratio control in the range of 1/9~1/15, in alcohol reflux, ethanol and magnesium interruption or continuously react
Manufacture method (JP3074341)；3rd, the alcoholic solution of the carboxylated magnesium after carboxylation is spray-dried, continues decarboxylation, come with this
Obtain the manufacture method (JP6087773) of fine round particle；4th, under conditions of saturation hydrocarbon, magnesium metal and ethanol
The manufacture method (JP6304815) to react；5th, Mg (OR)2Spray drying obtains suspended in ROH after disperseing in R'OH
Solids, then carry out that R'OH is distilled off again, the manufacture method (JP62051633) of obtained roundel.
Mechanical crushing can destroy the shape of particle script in method one.Provide that the ratio control of magnesium and ethanol exists in method two
In the range of 1/9~1/15, but study and find, if adding proportion is fixed on into 1/9, in the latter half reaction system of reaction
Viscosity can steeply rise, and when reactivity is more than 80%, if can be condensed without sufficiently stirring, particle, experiment is final not
Homogeneous round particle can be obtained；If stirred by force, the shape (JP8073388) of particle can be destroyed.If initial is added
Ratio is added to be fixed on 1/15 so that reaction occurs under conditions of amount of alcohol is more, in the terminal stage of reaction, when viscosity rises
When, although stirring can be smoothed out, obtained shape of particle can not enough justify, and bulk density is also very low, it is impossible to
To the particle for the condition that meets.In three to five various methods, operation is very complicated, and in addition to Mg and ROH, it is also necessary to other
Raw material, it is impossible to as meet require manufacture method.
