Embodiment 1
[0038] Add 2400g of commercially available simethicone oil with a viscosity (20°C) of 100cP into a 3000mL three-necked flask equipped with nitrogen protection, reflux condenser, mechanical stirring and thermometer, and then add 240g of ZnO which has been vacuum-dried at 150°C for 3h. powder, start stirring, and gradually raise the temperature from room temperature to 150° C. under the protection of nitrogen, and maintain at this temperature for 3 hours. After cooling down to room temperature, the mixture in the three-necked flask was filtered under reduced pressure, and the filtrate was collected.
[0039] Transfer the collected filtrate to a device for removing low boilers, blow a small amount of nitrogen gas into it, and when the absolute pressure of the system reaches 10Pa, gradually raise the temperature from room temperature to 200°C, and maintain it at 200°C for 4 hours to remove the filtrate. of low boilers. After the kettle liquid drops to room temperature, turn off t...
Embodiment 2
[0042]Weigh 100g of simethicone oil treated with ZnO at 150°C for 3h to a 250mL three-necked flask with reflux condenser, mechanical stirring and thermometer, add 0.0548g of nickel dimethylaminodithioformate (Ni atom and silicone oil The mass ratio is 0.000107: 1), 0.3475g of three (tetramethylcyclopentadiene) cerium (the mass ratio of Ce atom to silicone oil is 0.0009667: 1) and 4.0540g of tetrabutyl zirconate (the ratio of Zr atom to silicone oil The mass ratio is 0.00964:1), the stirring was started, the temperature was gradually raised from room temperature to 310°C, and maintained at 310°C for 15h. After cooling down to room temperature, filter, transfer the filtrate to the low boiling reaction kettle, feed a small amount of nitrogen (purity 99.9%) bubbling, when the absolute pressure of the system reaches 0.1Pa, gradually heat up from room temperature to 205 ° C, and Maintain at 205°C for 2h to remove low boilers in the filtrate and residual solvents in metal organic com...
Embodiment 3
[0044] Take by weighing 100g of the simethicone oil prepared in Example 1 at 150°C for 3h to a 250mL three-necked flask with a reflux condenser, a mechanical stirrer and a thermometer, and add 0.07g of dibutyldithiocarbamate Nickel (the mass ratio of Ni atom to silicone oil is 0.0000879:1), 0.2129g of cerium acetylacetonate hydrate (the mass ratio of Ce atom to silicone oil is 0.000655:1) and 3.5g of zirconium acetylacetonate (the mass ratio of Zr atom to silicone oil is 0.00655:1), start stirring, gradually raise the temperature from room temperature to 300°C, and maintain at 300°C for 12h. After cooling down to room temperature, filter, transfer the filtrate to the low boiling reaction kettle, feed a small amount of nitrogen (purity 99.9%) bubbling, when the absolute pressure of the system reaches 0.1Pa, gradually heat up from room temperature to 205 ° C, and Maintain at 205°C for 2h to remove low boilers in the filtrate and residual solvents in metal organic compounds.
