Put cyanuric chloride into the reaction kettle, add an appropriate amount of leveling agent and a small amount of hydrochloric acid, stir well, and add DSD sodium acid aqueous solution dropwise at -2 ℃ for condensation in an alkaline medium. After the reaction is completed, the material is pressed into a coupling reaction kettle and subjected to coupling reaction with p-aminobenzenesulfonic acid at 0-8 ℃. Finally, in the condensation kettle, the coupling product is condensed with diethylamine. After cooling, the product is salted out.
