摘要:

介绍一个国外大学有机化学实验——有机染料靛蓝(Indigo)的合成,及后续比较其对于不同的合成织物或天然纤维的染色情况。对实验中3方面问题进行了分析讨论,而这在国外的实验教材中并没有涉及到,即靛蓝合成过程的反应机理、靛蓝对纤维织物染色的原理以及关于靛蓝对纤维织物染色过程的讨论。该实验的设计值得借鉴于国内本科生有机化学实验。

Abstract:

The synthesis of organic dye Indigo followed by the application on the coloration of different fiber structures is introduced, as an undergraduate organic experiment widely employed overseas. Three confusing but important questions related to the synthesis procedure are also discussed, which are normally not mentioned in foreign textbooks: the synthetic mechanism for Indigo, the principle of Indigo coloration, and the process design of Indigo dyeing. The exquisitely designed procedure and practical achievement of this experiment are both worth applying to the domestic undergraduate experiments.
