摘　　要：通过DSD酸钠与三聚氯氰缩合 ,再分别与氨基苯磺酸盐和乙醇胺进行缩合 ,通过控制适当的温度和pH制得四磺酸基液体荧光增白剂。The liquor fluorescent whitening agent has been synthesized by DSD acid with trichloro-triazine, and then with sulfanilic acid and diethanolamine respectively. The results have been showed that the solubility of fluorescent whitening agent became easier in water because the affection of mult-sulfonate and mult-hydroxyl. It has been studied the affection of temperature and pH and time on the reaction in the process of synthesis. It has been also studied the applications in papermaking.
