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.
