【摘要】 以三聚氯氰、DSD酸(4,4’-二氨基二苯乙烯-二磺酸)和氨基化合物为原料,经过三步缩合反应得到一系列新型的酰胺基DSD酸-三嗪型荧光增白剂。对所得目标化合物进行了红外光谱、紫外可见光谱和荧光发射光谱等结构表征,同时对滤纸、棉布和麻布进行了增白性能检测。结果表明:化合物7a～7l对滤纸、棉布和麻布具有明显的增白效果,特别是对滤纸的增白效果更佳。更多还原

【Abstract】 A series of new DSD acid-triazine structure containing acylamino fluorescent brighteners(FBs) are synthesized through a three-step condensation reaction of cyanuric chloride,DSD acid and amino compound.The obtained compounds are characterized by IR spectrum,UV spectrum and fluorescence emission spectrum.The whiteness measurement is performed through dyeing filter paper,cotton and linen.The results show that compounds 7a-7l has the obvious whitening effect on the filter paper,cotton and linen.In particular,better whitening effect can be achieved on the filter paper.更多还原
