Reaction Conditions:
with sodium hydroxide at 70 - 85; pH=9.5; for 6 h;pH-value;Temperature;
Steps:
1.2; 2.2; 3.2; 4.2; 5.2; 6.2; 7.2; 1.2
(2) After the heat preservation is over, the temperature is lowered to below 70°C, 74.30g of cyclopropylamine is added, and then reheated to 85°C, and the temperature is kept and reacted for 6 hours. During the heating and holding period, 30wt% sodium hydroxide solution was used to adjust the pH to 9.5. After the reaction, the temperature was lowered to 30°C, filtered, and then beaten and washed with 400g water, then filtered, After drying, 173.69 g of cyromazine was obtained, the yield was 96.37%, and the purity by HPLC was 98.2%.
