Embodiment 1
[0032] Add 110.4g of cyanuric chloride and 600mL of acetone into a 3000mL four-necked bottle equipped with a reflux condenser, a thermometer, a stirrer, and a constant pressure dropping funnel, cool the four-necked bottle to -15°C, and slowly drop in 104.4 g Morpholine and 10w.t.% sodium hydroxide solution 480.0g, control the system temperature not to exceed 0°C. After dropping, the system was slowly warmed up to 40°C for 8 hours. Stop the reaction, add 77.6g of di-n-butylamine and 240.0g of 10w.t.% sodium hydroxide solution to the system, and react at 90°C for 10h. After the reaction, the crude product was filtered with suction, washed with distilled water, and dried at 100°C to obtain 208.9 g of a white product with a yield of 92.1%.
[0033] The structural formula of the product obtained in the present embodiment is as follows:

[0042] Add 110.4g of cyanuric chloride and 600mL of acetone into a 3000mL four-necked bottle equipped with a reflux condenser, a thermometer, a stirrer, and a constant pressure dropping funnel, cool the four-necked bottle to -15°C, and slowly drop in 104.4 g Morpholine and 10w.t.% sodium hydroxide solution 480.0g, control the system temperature not to exceed 0°C. After dropping, the system was slowly warmed up to 50°C for 8 hours. Stop the reaction, add 111.2g of di-n-hexylamine and 240.0g of 10w.t.% sodium hydroxide solution into the system, and react at 100°C for 10h. After the reaction, the crude product was filtered with suction, washed with distilled water, and dried at 100° C. to obtain 235.2 g of a white product with a yield of 90.3%.
[0043] The structural formula of the product obtained in the present embodiment is as follows:
[0044] .
[0045] pass 1 HNMR, confirmed the structure of the product. The indoor circuit test analysis shows that the product is con...

[0047] Add 110.4g of cyanuric chloride and 600mL of acetone into a 3000mL four-necked bottle equipped with a reflux condenser, a thermometer, a stirrer, and a constant pressure dropping funnel, cool the four-necked bottle to -10°C, and slowly drop in 104.4 g Morpholine and 10w.t.% sodium hydroxide solution 480.0g, control the system temperature not to exceed 0°C. After dropping, the system was slowly warmed up to 40°C for 8 hours. Stop the reaction, add 60.7g of diisopropylamine and 240.0g of 10w.t.% sodium hydroxide solution into the system, and react at 90°C for 10h. After the reaction, the crude product was filtered with suction, washed with distilled water, and dried at 100° C. to obtain 195.7 g of a white product with a yield of 93.2%.
[0048] The structural formula of the product obtained in the present embodiment is as follows:
[0049] .
[0050] pass 1 HNMR, confirmed the structure of the product. The indoor circuit test analysis shows that the product is conf...
