Embodiment 1
[0037] The present invention provides a kind of porous material B, the preparation steps are as follows:
[0038]Step S1, put 20mmol N,N-dimethyl n-octadecylamine and 20mmol epibromohydrin in a round-bottomed flask, stir for 10min, heat up to 70°C, and react with magnetic stirring for 2h. After the reaction, cool to room temperature, A white solid was produced, which was suction filtered, and the filter cake was washed 3 times with anhydrous ether, and dried in an oven at 40°C for 10 hours to obtain intermediate product 1;
[0039] Step S2, under the protection of nitrogen, add 50mmol of intermediate product 1 and 80mL of tetrahydrofuran into a three-necked flask, stir for 5min, add 10mL of taurine aqueous solution, and heat up to reflux for 2h at a rotation speed of 100r / min. After the reaction is completed, cool The solvent was spin-dried under vacuum at room temperature to obtain intermediate product 2, and the aqueous solution of taurine was prepared by mixing taurine and ...
Embodiment 2
[0045] The present invention provides a kind of porous material B, the preparation steps are as follows:
[0046] Step S1, put 20mmol N,N-dimethyl n-octadecylamine and 25mmol epibromohydrin in a round-bottomed flask, stir for 10 minutes, heat up to 70°C, and react with magnetic stirring for 2 hours. After the reaction, cool to room temperature, A white solid was produced, which was suction filtered, and the filter cake was washed 4 times with anhydrous ether, and dried in an oven at 42°C for 11 hours to obtain intermediate product 1;
[0047] Step S2, under the protection of nitrogen, add 50mmol of intermediate product 1 and 90mL of tetrahydrofuran into a three-necked flask, stir for 7min, add 10mL of taurine aqueous solution, and heat up to reflux for 3h at a rotation speed of 150r / min. After the reaction is completed, cool The solvent was spin-dried under vacuum at room temperature to obtain intermediate product 2, and the aqueous solution of taurine was prepared by mixing t...
Embodiment 3
[0053] The present invention provides a kind of porous material B, the preparation steps are as follows:
[0054] Step S1, put 20mmol N,N-dimethyl n-octadecylamine and 30mmol epibromohydrin in a round-bottomed flask, stir for 10 minutes, heat up to 70°C, and react with magnetic stirring for 2 hours. After the reaction, cool to room temperature, A white solid was produced, which was suction filtered, and the filter cake was washed 5 times with anhydrous ether, and dried in an oven at 45°C for 12 hours to obtain intermediate product 1;
[0055] Step S2, under the protection of nitrogen, add 50mmol of intermediate product 1 and 110mL of tetrahydrofuran into a three-necked flask, stir for 8 minutes, add 10mL of taurine aqueous solution, and raise the temperature to reflux for 4 hours under the condition of rotating speed of 200r / min. After the reaction, cool The solvent was spin-dried under vacuum at room temperature to obtain intermediate product 2, and the aqueous solution of ta...
