substituted active methylene compounds by classical Knoevenagel condensation reaction to obtain novel monostyryl dyes and a bis-styryl dye . These novel styryl dyes have hue varying from orange to violet. The dyes were applied to polyester fibers. The spectral and thermal characteristics of the dyes and fastness properties of the dyed polyester fabric were investigated. J. Heterocyclic Chem., 46, 221 (2009)
小说 通过经典的Knoevenagel缩合反应,合成了1,4-二乙基-1,2,3,4-四氢-7-甲氧基喹喔啉-6-甲醛,并与适当取代的活性亚甲基化合物进行缩合,得到了新型单苯乙烯基染料 和一种双苯乙烯染料 。这些新颖的苯乙烯基染料的色相从橙色到紫色不等。该染料被应用于聚酯纤维。研究了染料的光谱和热特性以及染色的聚酯织物的坚牢度。杂环化学杂志,46,221(2009)。
