三聚氯氰在荧光增白剂工业中的应用与展望

Application of Cyanuric Chloride in Fluorescent Brightener Industry

介绍用三聚氯氰合成的荧光增白剂,按其母体结构类型可分为以下几种:双三嗪氨基二苯乙烯类型、含三嗪基的香豆素类型、三嗪基芘类型、4-酰氨基-4’-三嗪氨基二苯乙烯类型。同时,简述了上述荧光增白剂的典型合成工艺及其主要用途。并预测今后十年内三聚氯氰在荧光增白剂中的消耗量仍以年均6%左右的速率递增。

The fluorescent brighteners synthesized based on cyanuric chloride are introduced. According to the main chemical structure, they are divided into several types,i, e. bis （triazinyl） amino stilbenes, triazinyl coumarins, triazinyl pyrenes, 4-amido-4＇ - triazinylaminostilbenes. Meanwhile,the typical synthetic technology of them and their main uses are summarized. And it is forecasted that the consumption of cyanuric chloride in manufacturing fluorescent brighteners will still increase progressively in the next decade with an increasing rate of 6%.
