【摘要】 合成了三种三价铬络合物NM－1、NM－2和NM－3，通过化学分析、色谱和光谱分析，证明三种络合物为目标产物；应用性能研究表明，NM－3在羊毛上的吸附速率较高，与酸性媒介黑T能进行较完全的络合物转化反应，因此NM－3作媒染剂进行羊毛毛条连续染色同浴媒时得色乌黑，色牢度较好。更多还原

【Abstract】 The Chromium(Ⅲ)-Complexes AM-1, NM-2 and NM - 3 was synthesized. The study results show that the absorptivity of AM - 3 on wool is higher than others and the reaction of NM - 3 and acid mordant dyes is more complete. Therefore by using NM - 3 as Mordant we can have a deeper black colour and better colourfastness.更多还原
