preparation example 1
[0047] A kind of antibacterial agent, its preparation steps are as follows:
[0048] 1) Add 2kg of maleic anhydride to 10kg of tetrahydrofuran, stir until dissolved, and raise the temperature to 45°C, then add 1.8kg of iminodiacetonitrile, divide the iminodiacetonitrile into three equal parts and add in sequence, two adjacent The time interval of each addition is 40min. After the addition is completed, stir and react for 2h, then add 2kg of saturated sodium hydroxide solution, stir and react for 2h, add 3kg of silver nitrate solution with a concentration of 3mol / L, and stir for 2h to obtain a mixed solution , the mixed solution is subjected to rotary evaporation, and the solid is washed three times with distilled water to obtain a silver-containing monomer;
[0049] 2) Add 2kg of triethylamine and 2.3kg of 3-bromo-1-propanol into 10kg of dichloromethane, stir until dissolved, and adjust the temperature to 5°C, then dropwise add 1.7kg of methacryloyl chloride , the dropping ra...
preparation example 2
[0053] A kind of antibacterial agent, its preparation steps are as follows:
[0054] 1) Add 2.5kg of maleic anhydride to 12kg of tetrahydrofuran, stir until dissolved, and raise the temperature to 47°C, then add 2.0kg of iminodiacetonitrile, and add the iminodiacetonitrile in four equal parts, adjacent The time interval between two additions is 35min. After the addition is completed, stir and react for 2.5h, then add 2.5kg of saturated sodium hydroxide solution, stir and react for 1.5h, add 3.5kg of silver nitrate solution with a concentration of 3mol / L, and stir for reaction After 2.5h, the mixed solution was obtained, and the mixed solution was subjected to rotary evaporation, and the solid was washed three times with distilled water to obtain the silver-containing monomer;
[0055] 2) Add 2.3kg of triethylamine and 2.7kg of 3-bromo-1-propanol into 15kg of dichloromethane, stir until dissolved, and adjust the temperature to 7°C, then dropwise add 1.8kg of methpropylene Acyl...
