我对不使用催化剂和分别使用几种不同催化剂做制取甲烷的实验作了比较。在实验中,每次取2克无水醋酸钠和4克烘干的碱石灰,连同催化剂混和均匀,放入硬质试管中用酒精灯加热。实验结果列表如下: I compared experiments using no catalysts and using several different catalysts to make methane. In the experiment, 2 grams of anhydrous sodium acetate and 4 grams of dried soda lime were taken at a time, and the mixture was evenly mixed with the catalyst and placed in a hard test tube and heated with an alcohol lamp. The list of experimental results is as follows:
