Embodiment 1
[0059] This embodiment relates to a method for preparing a metallocene, comprising the following steps:
[0060] 1) At room temperature, add 0.372g of ferrocene, 1.954g of anhydrous aluminum trichloride, 1.066g of dimethoxymethane and 20mL of 1,2-dichloroethane into a two-necked round-bottomed flask equipped with a reflux condenser and a thermometer. alkyl. After the obtained mixture was uniformly stirred by magnetic force, the temperature was raised to 45° C. under the protection of nitrogen, and kept at this temperature for 5 hours. Then the temperature was raised to 80°C and stirring was continued for 19 hours.
[0061] 2) After the reaction is terminated and cooled to normal temperature, add 50 mL of ethanol and stir for 1 hour, collect the crude product by filtration, wash with 10 wt% dilute hydrochloric acid and ethanol until the filtrate is colorless, and finally extract with ethanol in a Soxhlet extractor for 1 day . After drying under reduced pressure at 70°C, a br...
Embodiment 2
[0067] This embodiment relates to a method for preparing a metallocene, comprising the following steps:
[0068] 1) At room temperature, add 0.510g cyclopentadiene manganese tricarbonyl, 0.195g benzene, 1.217g anhydrous ferric chloride, 0.571g dimethoxymethane into a two-necked round bottom flask equipped with a reflux condenser and a thermometer and 20 mL of 1,2-dichloroethane. After the obtained mixture was uniformly stirred by magnetic force, the temperature was raised to 45° C. under the protection of nitrogen, and kept at this temperature for 5 hours. Then the temperature was raised to 80°C and stirring was continued for 19 hours.
[0069] 2) After the reaction was terminated and cooled to normal temperature, 50 mL of methanol was added and stirred for 1 hour. The crude product was collected by filtration, washed with methanol until the filtrate was colorless, and finally extracted with methanol in a Soxhlet extractor for 1 day. After drying under reduced pressure at 7...
Embodiment 3
[0075] This embodiment relates to a method for preparing a metallocene, comprising the following steps:
[0076] 1) At room temperature, add 0.255g cyclopentadiene manganese tricarbonyl, 0.195g benzene, 1.217g anhydrous ferric chloride, 0.571g dimethoxymethane into a two-necked round bottom flask equipped with a reflux condenser and a thermometer and 20 mL of 1,2-dichloroethane. After the obtained mixture was uniformly stirred by magnetic force, the temperature was raised to 45° C. under the protection of nitrogen, and kept at this temperature for 5 hours. Then the temperature was raised to 80°C and stirring was continued for 19 hours.
[0077] 2) After the reaction was terminated and cooled to normal temperature, 50 mL of methanol was added and stirred for 1 hour. The crude product was collected by filtration, washed with methanol until the filtrate was colorless, and finally extracted with methanol in a Soxhlet extractor for 1 day. After drying under reduced pressure at 7...
