【摘要】 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;介绍了4种合成该中间体的工艺路线,将该中间体7位上的氨基缩合环化、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.它们可广泛用于纺织印染、塑料加工等的增白.更多还原

【Abstract】 3-Phenyl-7-aminocoumarin is an important intermediate for the synthesis of 7-substituted coumarin fluorescent brighteners.4 synthetic routes were introduced for this intermediate.Some coumarin fluorescent brighteners containing imidazolyl and triazinyl groups were structured by the 7-amino group cyclic condensation and substitution of this intermediate.These brighteners are widely used for whitening in textile printing and dyeing,plastic processing etc.更多还原
