本实验证明了:(1)香豆素和四氢萘反应生成氢化香豆素;(2)氢化香豆素是一种比较稳定的产物,但在一定条件下可以进一步反应生成其它产物。文中给出了应用多种方法对中间物及产物的分析结果。动力学实验及产物分析结果表明氢化香豆素的大多数反应步骤是按连串反应进行。本文提出的反应机理较好地解释了实验现象。
The experiment proves: (1) coumarin and tetrahydronaphthalene react to produce hydrogenated coumarin; (2) hydrogenated coumarin is a relatively stable product, but under certain conditions can further react to generate other products. In this paper, the results of the analysis of intermediates and products using a variety of methods are given. Kinetic experiments and product analysis showed that most of the reaction steps of hydrogenated coumarin are carried out in a series of reactions. The reaction mechanism proposed in this paper is a good explanation of the experimental phenomenon.
