Synthetic example

[0058] Synthesis of compound 12,2-bis(methoxymethylene)-1,3-dimethoxypropane:

[0059] 1) Synthesis of 2-((2-phenyl)-1,3-dioxcyclohexyl)-1,3-propanediol:

[0060] 54.4g of pentaerythritol (Mw=136.15, 0.4mol) was dissolved in 500mL of water. Raise the temperature to 40°C, add 42.4g benzaldehyde (Mw=106, 0.4mol) and 2mL concentrated hydrochloric acid, and stir for 6 hours. The reaction system was left standing overnight. Suction filtration, add 800mL water and 0.5g potassium carbonate to the filter cake, stir and raise the temperature to dissolve, cool and crystallize. After filtration, the crude product was dried under vacuum at 75°C. Crude toluene was recrystallized, and the final product was 72.6 g, with a yield of 81%.

[0061] 1 H NMR (CDCl 3 / TMS,300MHz)δ(ppm):3.56(s,4H,-C(CH 2 Oh) 2 ),3.76,3.79(s,4H,-C(CH 2 O) 2 CH-),5.44(s,1H,phCH-),7.37-7.39(m,5H,C 6 h 5 CH-).

[0062] 2) Synthesis of 2-((2-phenyl)-1,3-dioxcyclohexyl)-1,3-dimethoxypropane:

[0063] 20g of ...

Embodiment 1

[0091] Magnesium alkoxide preparation:

[0092] In a 1L reactor equipped with a stirrer, a reflux condenser, a thermometer, and a burette, after fully replacing with nitrogen, 550 mL of ethanol, 10 mL of isopropanol, and 0.68 g of iodine were dissolved in the reactor. After stirring, the temperature was raised until reaching the reflux temperature of the reaction system. Then add magnesium powder 32g successively; React until no hydrogen is discharged. Then wash, filter and dry to obtain a bulk density of 0.25g / cm 3 , 147 g of magnesium alkoxide with an average particle diameter (D50) of 47.0 μm.

[0093] Preparation of solid catalyst component:

[0094] Take 10g of the alkoxymagnesium carrier prepared above, 50mL of toluene and 2.5g of the internal electron donor (compound 1) to prepare a suspension; add 40mL of toluene and four Titanium chloride 60mL, then add the prepared suspension into the kettle, raise the temperature to 80°C, keep the temperature constant for 1 hour...

Embodiment 2-6

[0098] The steps are the same as in Example 1, except that the internal electron donors are replaced with compounds 2-6 in the preparation of the solid catalyst component, and the dosage is 2.5 g.

Abstract

The invention discloses a compound with a novel structure. The structure of the compound is represented by formula (I); and in the formula (I), R1 to R4 can be same to or different from each other and are independently selected from substituted or non-substituted C1-C20 alkyl groups, and preferably substituted or non-substituted C1-C10 aliphatic groups, C3-C10 cycloalkyl groups, C6-C20 aryl groups and C7-C20 alkaryl groups, and R3 and R4 can be optionally connected to form a ring. The compound represented by formula (I) can be used as an internal electron donor compound to obtain a catalyst with excellent comprehensive performances. The catalyst can be used in olefin polymerization, especially propylene polymerization to obtain a satisfactory polymerization yield, has good hydrogen sensitivity and high stereospecificity, and is in favor of developing different types of polymers.

Description

technical field [0001] The invention relates to the field of olefin polymerization, in particular to a compound with a new structure that can be used as an internal electron donor compound and a catalyst solid component containing the compound. The present invention also relates to a catalyst comprising said solid catalyst component and its use in the polymerization of olefins, especially in the polymerization of propylene. Background technique [0002] A solid titanium catalyst component based on magnesium, titanium, halogen and an electron donor, known in the art as a Ziegler-Natta catalyst, can be used for CH 2 =CHR olefin polymerization, especially in the polymerization of α-olefins with 3 or more carbon atoms, can obtain polymers with higher yield and higher stereoregularity. It is well known that internal electron donor compounds are one of the essential components in Ziegler-Natta catalyst components. From the early disclosed monobasic carboxylic acid ester compound...
