DICHLOROISOCYANURIC ACID synthesis

Yield:2782-57-2 96%

Reaction Conditions:

with hypochlorous anhydride in water; pH=2 at 15 - 25; for 6 h;Large scale;Temperature;

Steps:

2.1; 2.2; 2.3 Example 2
(1) adding 2kg of cyanuric acid into 18L water at 25 DEG C, stirring uniformly to obtain the cyanuric acid aqueous slurry;(2) at 15 ° C,1.41kg will be addedDichloro monoxideInto the cyanuric acid aqueous slurry,Access time is 1.5h,And then continue the reaction until the pH of the reaction system is 2, the reaction is completed,Since the passage of chlorine dioxide to the end of the reaction time-consuming 6h, to obtain a reaction solution containing dichloroisocyanurate.(3) The above reaction solution was quickly filtered, the filtrate can be returned to step (1) instead of solvent water for recycling,The solid was washed with water, and then dried at 110 3h, to give the target dichloroisocyanuric acid,Its effective chlorine content of 70.0%, cyanuric acid as a benchmark, the yield was 96%.
