最后一种方法,试剂来源容易且价格低,操作方法简便,是当今实验室制备甲烷应用最普遍的方法,也是中学有机化学教学所必须要做的一个学生实验。 但是,该法无水醋酸钠和碱石灰的用量比,各家说法不一。例如: 中学统编教材高中化学课本第二册上介绍所用无水醋酸钠与碱石灰的用量比是1:3; The last method, with easy-to-source and low-cost reagents and easy-to-use methods, is the most commonly used method for preparing methane in today’s laboratories and is a student experiment that must be done in organic chemistry teaching in secondary schools. However, the method of anhydrous sodium acetate and soda than the amount of each different opinions. For example: high school textbooks compiled high school chemistry textbooks introduced on the second volume of anhydrous sodium acetate and soda lime ratio of 1: 3;
