摘要:基于相似相溶原理,以 1,4-二氨基-2,3-二羧酸酐蒽醌为原料,与不同碳链长度伯胺进行取代反应制备了 8
种油溶性 1,4-二氨基-2,3-邻苯二甲酰亚胺蒽醌类蓝色染料。对合成的 8 种染料在常见有机溶剂中的溶解度和紫
外吸收性能进行了测试,结果表明,8 种产物的最大吸收波长均在 669~672 nm,不受产物中烷基链长度的影响。
染料的油溶性相对于 1,4-二氨基-2,3-二羧酸酐蒽醌得到明显提升。其中,1,4-二氨基-2,3-二羧酸酐蒽醌在四氢呋
-3
喃等有机溶剂中不溶,产物 Anthra-n-6(正己胺取代)在四氢呋喃中的溶解度最大,可达到 9×10 g/mL(25 ℃)。
1,4-二氨基-2,3-二羧酸酐蒽醌无法作为打印染料,而 Anthra-n-6 打印效果最好,打印的色密度值为 1.17,L、a、
b 值分别为 79.7、10.2、25.9。

Abstract: Based on the principle of like dissolves like, 1,4-diamino-2,3-dicarboxylic anhydride anthraquinone
was used as raw material to prepare eight oil-soluble 1,4-diamino-2,3-phthalimide anthraquinone dyes by
substitution reaction with primary amines of different carbon chain lengths. The solubility and UV
absorption properties of the synthesized 8 dyes in common organic solvents were tested. The results show
that the maximum absorption wavelength of the eight products was in the range of 669~672 nm, which
was not affected by the alkyl chain length. The oil solubility of dyes was significantly improved compared
with that of 1,4-diamino-2,3 dicarboxylic anhydride anthraquinone. Among them, 1,4-diamino-2,3-
dicarboxylic anhydride anthraquinone was insoluble in tetrahydrofuran, and product Anthra-n-6 (n-hexylamine
3
substituted) had the highest solubility in tetrahydrofuran, which reached 9 × 10 g/mL (25 ℃ ).
1,4-Diamino-2,3-dicarboxylic anhydride anthraquinone was not used as printing dye, while Anthra-n-6
exhibited the best printing effect. The printed density value was 1.17, L, a and b values were 79.7, 10.2,
and 25.9, respectively.
