Embodiment 1
[0053] This embodiment is an anti-wrinkle monomer, and the preparation method of the anti-wrinkle monomer is as follows:
[0054] A1: Add p-chloronitrobenzene, p-phenylenediamine, potassium carbonate, phase transfer catalyst, copper oxide, and half of xylene to a four-way tank equipped with a magnetic stirrer, thermometer, water separator, air guide tube, and reflux condenser. In the flask, heated in an oil bath, stirred and reacted for 7 hours at a temperature of 180°C and a stirring rate of 200r / min, added the remaining xylene under the condition of cooling to 110°C after the reaction, stirred at a constant temperature for 30min, and cooled to 80 Add hot water at 60°C under the condition of ℃, let it stand for 1h, separate layers, collect the organic phase and wash with distilled water, and rotate to evaporate to obtain intermediate 1; control p-chloronitrobenzene, p-phenylenediamine, potassium carbonate, phase transfer The dosage ratio of catalyst, copper oxide, xylene and ...
Embodiment 2
[0061] This embodiment is an anti-wrinkle monomer, and the preparation method of the anti-wrinkle monomer is as follows:
[0062] A1: Add p-chloronitrobenzene, p-phenylenediamine, potassium carbonate, phase transfer catalyst, copper oxide, and half of xylene to a four-way tank equipped with a magnetic stirrer, thermometer, water separator, air guide tube, and reflux condenser. In the flask, heated in an oil bath, stirred and reacted for 9 hours at a temperature of 190°C and a stirring rate of 400r / min, added the remaining xylene under the condition of cooling to 120°C after the reaction, stirred at a constant temperature for 50min, and cooled to 85 Add hot water at 80°C under the condition of ℃, let it stand for 2h, separate layers, collect the organic phase and wash with distilled water, and rotary evaporate to obtain intermediate 1; control p-chloronitrobenzene, p-phenylenediamine, potassium carbonate, phase transfer The dosage ratio of catalyst, copper oxide, xylene and hot...
Embodiment 3
[0069] This embodiment is a pollution-resistant monomer, and the preparation method of the pollution-resistant monomer is as follows:
[0070]Add 2,2,3,3-tetrafluoropropanol and phenothiazine into a three-necked flask equipped with a magnetic stirrer, a thermometer and a constant pressure dropping funnel, and gradually stir while stirring at a stirring rate of 200r / min. Add acryloyl chloride dropwise, and control the dropping rate to 1 drop / s. After the dropwise addition, continue to stir and react for 2 hours under the condition of raising the temperature to 65°C, and then continue stirring and reacting for 2 hours under the condition of raising the temperature to 85°C. After the reaction, the reaction product is Wash with sodium hydroxide solution and distilled water until neutral, then distill under reduced pressure, collect fractions at 56.5°C to obtain stain-resistant monomers; The dosage ratio is 100mL: 2.0g: 118.2g, and the mass fraction of sodium hydroxide solution is ...
