摘　　要：乙酸钠、氢氧化钠、氧化钙研磨混合法制备甲烷气体的实验存在反应速率慢、产率低、试管易破裂及不易清洗等问题。基于此,在反应物不变的情况下,采用溶剂混合法,可实现快速、高效制备甲烷气体,同时也解决了试管破裂、不易清洗等问题。该方法解决了以往制备甲烷气体的不足,可有效应用于化学实验中。There are some problems in the experiment of preparing methane gas by grinding and mixing sodium acetate,sodium hydroxide and calcium oxide,such as slow reaction rate,low yield,easy cracking and difficult cleaning of test tube.Based on this,the solvent mixing method can achieve rapid and efficient preparation of methane gas and solve rupture and difficult cleaning problems for tubes.This method essentially solves the shortcomings of the preparation of methane gas,and can be effectively applied to chemical experiments.
