还原黄3RT合成工艺优化

Synthesis Optimization of the Vat Yellow 3RT

以邻二氯苯为溶剂,合成了还原染料还原黄3RT,并对合成工艺进行了优化。优化条件为:反应温度为180℃,保温3 h,n(四氯化钛)∶n(亚胺)=2.0∶1,在此条件下,目标产物测试后的色光和相对强度符合标准要求。采用红外光谱(IR)进行分析和结构表征。

The adjacent O-dichlorobenzene as solvent,Synthesis of vat dye vat yellow 3RT,and the synthesis process was optimized.Optimization of conditions for： the reaction temperature was 180 ℃,insulation 3 hours.Titanium tetrachloride and imine molar ratio was 2.0∶1,on this condition,the target product testing after shade and relative strength meets the requirements of the standard.The determination of Infrared spectroscopy（IR）Analysis and structure characterization.
