摘要

三聚氯氰与4

4′-二氨基二苯乙烯-2

2′-二磺酸和两种氨基化合物经过三步缩合反应得到三嗪基氨基二苯乙烯型荧光增白剂，用三乙醇胺和三乙胺分别替代二乙醇胺和二乙胺，合成新型两性季铵盐类荧光增白剂，研究其与对比的非季铵盐类荧光增白剂的应用性能和在水溶液中的紫外吸收性能、光致异构化现象、荧光发射性能及其应用性能.结果表明：该季铵盐类增白剂耐酸碱性能明显提高，使用范围扩大，但其紫外吸收和荧光发射性能下降，且同样存在较为明显的光致异构化现象，耐光性也较差.

Abstract

Triazinyl aminostilbene fluorescent brighteners (FBs)can be synthesized through three-step condensation reaction of 4

4′-diamino stilbene-2

2′-disulfonic acid (DSD acid) with cyanuric chloride (CC) and two amino compounds.The quaternary ammonium salt fluorescent brighteners were synthesized by changing reactants of the third condensation reaction.Triethylamine and triethanolamine were used to replace diethylamine and diethanolamine.The ultraviolet ray absorption in solutions

photoinduced isomerization phenomena

fluorescence emission properties and application properties of quaternary ammonium salt FBs and nonquaternary ammonium salt FBs were investigate.The acid/alkali resistance of quaternary ammonium salt FBs was higher and the application was wider

but the ultraviolet ray absorption and fluorescence emission performance were lower than those of nonquaternary ammonium salt FBs.At the same time

quaternary ammonium salt FBs had obvious phenomena of photoinduced isomerization and its light stability was also low.
