高二化学课本中测定乙醇分子结构的实验,是从定量观点推测乙醇分子结构的课堂实验。但是中学化学教师反映,按照课本的方法进行实验其结果很不理想,氢气产量大大少于理论产量,难以证明乙醇的实际结构。本文从试剂和仪器装置两个方面对该实验加以研究改进,取得了较满意的结果。
The experiment of determining the molecular structure of ethanol in the textbook of the high school chemistry is a classroom experiment that estimates the molecular structure of ethanol from a quantitative point of view. However, chemistry teachers at middle school report that the results of the experiments conducted in accordance with the textbook method are very unsatisfactory. The hydrogen production is much less than the theoretical output, and it is difficult to prove the actual structure of ethanol. This article studied and improved the experiment from two aspects of reagents and instrumentation, and achieved satisfactory results.
