Embodiment 1
[0097] 1) 2.0g anhydrous magnesium chloride MgCl 2 Disperse with 5.5ml of isooctyl alcohol in 50ml of decane, heat to 130°C to form a transparent solution, and react at 130°C for 2.0 hours to obtain magnesium chloride alcoholate;
[0098]Add the above-mentioned magnesium chloride alcoholate dropwise into a suspension of 3.0g spherical clay carrier and 50ml decane, react at a constant temperature of 60°C for 4.0 hours, then filter off the liquid, wash the filtered solid three times with decane, and dry Obtain the magnesium composite of clay catalyst carrier;
[0099] 2) Add 5.0 g of the magnesium complex supported by the clay catalyst to 100 ml of titanium tetrachloride solution at -20°C, and react at a constant temperature at -20°C for 1.0 hour. Slowly raise the temperature to 120°C, add 0.2ml of diisobutyl phthalate, then react at a constant temperature at 120°C for 1.5 hours, filter the liquid after the reaction is completed, add 100ml of titanium tetrachloride solution aga...
Embodiment 2
[0121] 1) 2.0g anhydrous magnesium chloride MgCl 2 Disperse with 12.5ml of ethanol in 50ml of decane, heat to 110°C to form a transparent solution, react at 110°C for 2.0 hours to obtain the alcoholate of magnesium chloride;
[0122] The magnesium chloride alcoholate was added dropwise to a suspension of 3.0 g of spherical clay carrier and 50 ml of decane, reacted at a constant temperature of 110° C. for 4.0 hours, then filtered off the liquid, and the filtered solid was washed 3 times with decane. After drying, the magnesium composite of the clay catalyst carrier is obtained;
[0123] 2) Add 5.0 g of the magnesium complex supported by the clay catalyst to 100 ml of titanium tetrachloride solution at -20°C, and react at a constant temperature at -20°C for 1.0 hour. Slowly raise the temperature to 120°C, add 2.0 g of fluorene diether, and then react at a constant temperature of 120°C for 1.5 hours. After the reaction is completed, the liquid is filtered off, and 100ml of titan...
Embodiment 3
[0137] 1) 2.0g anhydrous magnesium chloride MgCl 2 Disperse with 2.8ml of isooctyl alcohol in 50ml of decane, heat to 130°C to form a transparent solution, and react at 130°C for 4.0 hours.
[0138] Add the above-mentioned magnesium chloride alcoholate dropwise into a suspension of 3.0g spherical clay carrier / 10ml decane, react at a constant temperature of 60°C for 10.0 hours, then filter off the liquid, wash the filtered solid three times with decane, and dry A magnesium composite supported by a clay catalyst is obtained.
[0139] 3) Add 5.0 g of magnesium complexes supported by spherical clay catalysts to 100 ml of titanium tetrachloride solution at -20°C, and react at a constant temperature at -20°C for 1.0 hour. Slowly raise the temperature to 120°C, add 0.1ml of ethyl benzoate, then react at a constant temperature at 120°C for 2.0 hours, filter the liquid after the reaction is completed, add 100ml of titanium tetrachloride solution again, and react at a constant temperat...
