荧光增白剂化学结构中二苯乙烯双键的合成

Synthesis for Stilbene Double Bond in the Chemical Structure of Fluorescent Brightener

二苯乙烯在荧光增白剂的化学结构中占有重要地位。通过以甲苯衍生物的氧化偶联反应、苄基氯衍生物的消除二聚反应及Wittig-Horne反应,叙述了二苯乙烯双键的合成方法以及重要品种的技术进展。

Stilbene plays an important role in the chemical structure of fluorescent brighteners. Stilbene derivatives can be prepared by oxidative coupling of toluene derivatives, eliminative dimerization of benzyl chloride derivatives and Wittig-Home reaction. The synthe- sis method of stilbene double bond and the technological progress of important fluorescent brighteners were described.
