摘要:

通过对经典基础有机化学实验——甲基橙制备实验的衍生,将合成制备反应与光谱分析结合,设计成小综合实验,以达到学科交叉的目的。改良后的实验有利于学生对偶氮苯类化合物性质的进一步认识,提高固体有机化合物的合成操作技能,同时还可掌握光谱分析方法与科学前沿知识,拓宽基础实验训练的单一性,有助于培养学生科学思维方法。

Abstract:

Preparation of methyl orange is regarded as a classical basic experiment in organic chemistry. Based on the derivation of methyl orange preparation, we design a mini comprehensive experiment by combining the synthetic experiment of azobenzene compounds with spectral analysis to achieve the multi-disciplinary interactions. It not only can guide students to further understand properties of azobenzene compounds, but also can help to improve the synthetic operation skills of solid organic compounds and master the spectral analysis methods. In the meantime, we hope to break the limitation of basic experimental training and make it easier for students to cultivate scientific thinking methods.

Key words: Methyl orange, Azobenzene compounds, Teaching improvement
