This paragraph synthesis method
1. The reaction is carried out by heating the reaction with ammonium chloride and urea, acidifying, alkali-dissolving, chlorination, and drying.
2. It is prepared by using isocyanuric acid, sodium hydroxide and chlorine as raw materials.
3. Sodium hydroxide and cyanuric acid were sequentially added to the chlorination kettle at a molar ratio of 2:1. The p H value is 6.5 to 8.5, and the chlorine gas is continuously chlorinated at a temperature of 5 to 10 ° C to obtain dichloroisocyanuric acid, which is neutralized with sodium hydroxide to obtain a sodium salt.
4. Cyanuric acid is reacted with chlorine gas and the like.
