摘要
设计合成了2个以醛基为活性基团的蛋白质纤维专用活性染料ARD-1和染料ARD-2。通过对合成条件的单因素优化试验,得出合成ARD-1的最佳条件是n茜素红∶n氯丁醛∶V二甲基亚砜=1∶2∶10,反应温度30℃,反应时间24h;合成ARD-2的最佳条件是n茜素黄∶n氯丁醛∶V二甲基亚砜=1∶2∶10,反应温度40℃,反应时间24h;在此条件下,它们的收率分别为75.4%和74.6%。采用FT-IR和UV-Vis分别对原料和目标产物的波谱特性进行了对比分析。
Two kinds of reactive dyes with aldehyde as reactive groups for protein fibers, which named as ARD - 1 and ARD - 2, were synthesized. The best synthesis conditions of ARD - 1 are as follows : nalizarin red :nα - chloro b utanal:VDMF = 1:2:10, T = 30℃ , t = 24h ; The best synthesis conditions of ARD - 2 are as follows : nAlizarin yellow GG :nα-chloro butanal : VDMF = 1:2:10, T = 40℃, t = 24h ; At these conditions, their yields are 75.4% and 74.6% separately. FT - IR and UV - vis are applied to identity the raw materials and the target products.
