3-苯基-7-氨基香豆素和香豆素类型荧光增白剂

3-Phenyl-7-amino Coumarin and Coumarin Fluorescent Brightener

3-苯基-7-氨基香豆素是合成3,7-取代香豆素类型荧光增白剂的重要中间体。文章首先介绍了四种合成该中间体的工艺路线,再将该中间体7-位上的氨基缩合环化和取代构成一些含唑基的香豆素类型荧光增白剂和一些含三嗪基的香豆素类荧光增白剂。它们广泛用于纺织印染、塑料加工等的增白。

3- Phenyl- 7 -amino coumarin was an important intermediate of 3,7 -substitutional coumarin fluoresent brightener. Four kinds of synthesis process of the intermediate was introdued, firstly. And then some coumarin fluorescent brighteners containing zole or triazine group were prepared from the intermediate by condensation, cyclization. They were widely applicated on the brighteness of textiledyeing and plastic etc.
