Embodiment 1
[0023] Present embodiment 1 provides a kind of modified nano silicon dioxide, is made by the following steps:
[0024] Step A1, put 0.1mol 4-aminodiphenylamine, 0.1mol epichlorohydrin and 65.8mL DMF in a three-necked flask, under nitrogen protection, heat up to 50°C, stir for 4 hours, after the reaction, add deionized water to wash , then extracted with ethyl acetate, and the ethyl acetate was removed by rotary evaporation to obtain intermediate 1;
[0025] Step A2: Add 0.1 mol of triphenylphosphine into 50 mL of acetone, stir the reaction at 200 r / min, add 5 mL of the acetone solution of Intermediate 1 dropwise while stirring, and control the dropping rate at 1 drop / second. After the addition, Stirring and reacting for 3 hours, a white precipitate was formed, filtered, and the filter cake was washed with deionized water for 3 times, then dried to constant weight at 60°C to obtain Intermediate 2, and the acetone solution of Intermediate 1 was prepared from Intermediate 1 and a...
Embodiment 2
[0029] Present embodiment 1 provides a kind of modified nano silicon dioxide, is made by the following steps:
[0030] Step A1, put 0.1mol 4-aminodiphenylamine, 0.1mol epichlorohydrin and 68.2mL DMF in a three-necked flask, under the protection of nitrogen, heat up to 55°C, stir for 5 hours, after the reaction, add deionized water to wash , then extracted with ethyl acetate, and the ethyl acetate was removed by rotary evaporation to obtain intermediate 1;
[0031] Step A2: Add 0.1 mol of triphenylphosphine into 55 mL of acetone, stir the reaction at a speed of 250 r / min, add 5.2 mL of the acetone solution of intermediate 1 dropwise while stirring, and control the dropping rate at 2 drops / second, after the addition is completed , stirred and reacted for 4 hours, a white precipitate appeared, filtered, and the filter cake was washed 4 times with deionized water, and then dried to constant weight at 60°C to obtain Intermediate 2. The acetone solution of Intermediate 1 was prepare...
Embodiment 3
[0035] Present embodiment 1 provides a kind of modified nano silicon dioxide, is made by the following steps:
[0036] Step A1, put 0.1mol 4-aminodiphenylamine, 0.1mol epichlorohydrin and 71.2mL DMF in a three-necked flask, under the protection of nitrogen, heat up to 60°C, stir for 6 hours, after the reaction, add deionized water to wash , then extracted with ethyl acetate, and the ethyl acetate was removed by rotary evaporation to obtain intermediate 1;
[0037] Step A2: Add 0.1 mol of triphenylphosphine into 60 mL of acetone, stir the reaction at 300 r / min, add dropwise 5.5 mL of the acetone solution of Intermediate 1 while stirring, and control the dropping rate to 3 drops / second. , stirred and reacted for 5 hours, a white precipitate was produced, filtered, and the filter cake was washed with deionized water for 5 times, then dried to constant weight at 60°C to obtain intermediate 2, the acetone solution of intermediate 1 was prepared from intermediate 1 and acetone accor...
