氨的合成原是高一化学中的一个较大型的难点实验.由于一般书中所介绍的方法,实验装置复杂,操作手续烦琐,加之使用的催化剂活性较差,往往实验效果不明显,因此,实际上很少学校化学教学中曾做过这一实验。现行教材甚至已将该实验删去.我们认为,氨是中学化学教学的重点内容之一,通过氨的合成实验,可以帮助学生理解合成氨的工业生产原理和通过鉴定合成的氨能帮助学生掌握氨的性质。为此目的,我们对该实验进行了一些探索和
The synthesis of ammonia was originally a large high-chemistry one of the difficult experiment.Because the method described in the general book, the experimental device is complex, cumbersome procedures, combined with the use of the catalyst activity is poor, the experimental results are often not obvious, therefore, In fact, few have done this experiment in school chemistry teaching. The current textbook has even deleted this experiment.We think that ammonia is one of the key contents of chemistry teaching in middle school. Through the synthesis experiment of ammonia, it can help students to understand the industrial production principle of synthetic ammonia and help the students master the ammonia through the identification of synthetic ammonia The nature of To this end, we have done some research on this experiment
