Embodiment 1

[0072] Synthesis of embodiment 1 fluorene-9-methyl formate-9-ethyl formate

[0073] Step A: Add 18g of sodium hydride, 50g of fluorene, and 150mL of toluene to a 1000mL three-necked flask in sequence under nitrogen protection, turn on mechanical stirring, heat up to 125°C under reflux, and keep the reaction for 4h; cool down to 90°C, and slowly add 146.1 g diethyl carbonate, drop it within 1.5 hours, and continue to react for 3 hours after the drop; cool to 20°C, slowly add a mixture of 60g concentrated hydrochloric acid and 75g water, and control the temperature not to exceed 40°C; filter and separate the organic phase, washed with water until neutral, and the organic phase was rotary evaporated to obtain a reddish-brown liquid; the liquid obtained by rotary evaporation was refluxed overnight with 157.4g of acetic acid and 63g of 10% hydrochloric acid; the mixture was lowered to 20°C and separated; the organic phase was rotary evaporated Then add 30% NaOH solution to adju...

Abstract

The invention provides a catalyst component for olefin polymerization. The catalyst component comprises Mg, Ti, halogen and an electron donor, wherein the electron donor is selected from at least one unsaturated ring substituted di-acid ester compound as shown in a general formula (I). The invention also provides a catalyst containing the catalyst component and an application of the catalyst in olefin polymerization, and particularly in propylene polymerization. The specific ring substituted di-acid ester compounds in the catalyst component have a positive effect on formation of the catalyst activity center and improvement of the stereoselectivity of the catalyst.

Description

technical field [0001] The present invention relates to a method for CH 2 = CHR solid catalyst component for olefin polymerization, wherein R is hydrogen or a hydrocarbyl group containing 1-12 carbon atoms, more particularly, the present invention relates to a component containing at least one special type of ring-substituted malonate compound Catalyst components, catalysts containing the catalyst components and the use of the catalysts in the polymerization of olefins, especially in the polymerization of propylene. Background technique [0002] Electron donor compounds can change the properties of the active center of olefin polymerization Ziegler-Natta catalysts to the greatest extent, thereby changing the performance of the catalyst to the greatest extent, so the research on high-efficiency Ziegler-Natta catalysts is in a sense Research on better electron donors. At present, domestic and foreign research on internal electron donors mainly focuses on traditional fatty ac...
