5,7-Dihydroxy-4,8-dimethylchromen-2-one was synthesized based on methyl phloroglucinol and its spectral and physicochemical characteristics were obtained. Reactions of the newly synthesized coumarin with different diazonium salts were studied, conditions allowing selective obtaining the corresponding monoor bisazo compounds were found. The synthesized azo compounds dye nylon in the yellow-brown colors under standard coloration conditions, providing high stability of obtained colors upon exposure to physicochemical conditions.
以甲基氯葡萄糖醇为基础合成了 5,7-二羟基-4,8-二甲基香豆素-2-酮,并获得了其光谱和理化特性。研究了新合成的香豆素与不同重氮盐的反应,找到了选择性获得相应的单门双偶氮化合物的条件。在标准着色条件下,合成的偶氮化合物可将尼龙染成黄棕色,在暴露于物理化学条件下,所获得的颜色具有很高的稳定性。
