摘要
以邻二氯苯为溶剂,1,5-二(N-蒽醌基)氨基蒽醌(以下简称蒽醌亚胺)为原料,合成了还原染料还原橙RT。优化条件为:反应温度为160℃,保温3h,n(四氯化钛)∶n(蒽醌亚胺)=1.8∶1,在此条件下,收率达到82.1%,采用红外光谱进行分析和结构表征,目标产物的色光和相对强度符合标准要求。
1,5-Diamno（N-anthraquinonyl）-anthraquinone（hereinafter referred to as anthraquinone im- ine） was used as raw material to synthesize vat dye vat orange RT with adjacent O-dichlorobenzene as solvent, and the synthesis process was optimized. Optimization conditions were as follows： the reac- tion temperature was 160 ℃ ,insulated for 3 hours, n（titanium tetrachloride） ： n（anthraquinone im- ine）=1. 8 ： 1. Under these conditions, the yield could reach 82. 1%, which increased above 20%. The shade and relative strength of the tested target product could meet the standard. Infrared spec- troscopy was used for analysis and structure characterization.
