蒽醌型离子染料的合成及应用

Syntheses and Application of Cationic Dyes of Anthraquinone

[3 - ( 1-氨基 - 2 -溴 - 4 -氨基蒽醌 )丙基 ]三甲氨基甲基硫酸盐阳离子染料的合成 ,可通过1-氨基蒽醌溴化 ,与N ,N -二甲氨基丙胺缩合 ,再与硫酸二甲酯季胺化合成为水溶性染料。该染料最大吸收波长为 60 8nm(甲醇液中 ) ,熔点 2 2 8～ 2 3 0℃。上染聚丙烯纤维。使纤维呈绿光蓝色 ,日晒牢度为

amimo-2-bromo-4-anthraquinonylamino)-propyl]trimethylammonium methosufate, The blue powder dyes by 1-amino-anthraqumone bromize, with Me 2NCH 2CH 2CH 2NH 2, with Me 2SO 4 was prepared, soluble in water. The results show that the maximum absorption of the dyes is at 608nm in methanol. T mp =228～230℃. The dyes are suitable for dyeing Orlon acrylin fiber, giving clear virid bluish. The fastness of sunlight intensity is seven level.
