硝基苯是一种制造染料及医药品的重要物质,合成的途径是用浓硝酸和浓硫酸混合物对苯进行硝化,这一方法亦成为中学及大学实验室制备硝基苯的方法,但是,由于实验中使用的硝化试剂为两大强酸,给实验者特别是学生带来一定程度的危害,影响实验的安全性,为了提高苯硝基化实验教学的安全可靠性,笔者针对非强酸性苯硝化试剂及方法进行了研究,实验表明,如果用水合 Nitrobenzene is an important substance in the manufacture of dyes and pharmaceuticals. The way to synthesize nitrobenzene is nitration of benzene with a mixture of concentrated nitric acid and concentrated sulfuric acid. This method has also become a method of preparing nitrobenzene in high school and university laboratories. However, As the nitrification reagents used in the experiment are two major strong acids, which will bring a certain degree of harm to the experimenters, especially the students, and affect the safety of experiments. In order to improve the safety and reliability of the teaching of benzene nitration experiments, Nitration reagents and methods were studied, experiments show that if hydration
