1实验室用醋酸钠晶体与碱石灰共热制取甲烷分析：因为醋酸钠晶体中含有结晶水，水的存在使甲烷难于生成。试管容易破裂，而且伴随有副反应。产物中有一定量的丙酮，燃烧时火焰呈黄色，偏差大。原因是加热温度过高，醋酸钠分子发生双分子分解，生成丙酮。为除去反应中的副产物丙 1 Laboratory use of sodium acetate crystals with soda lime to produce methane analysis: Because of the crystal water contained in the sodium acetate crystal, the presence of water makes it difficult to generate methane. The test tube is apt to rupture and is accompanied by side reactions. There is a certain amount of acetone in the product, the flame is yellow when burning, and the deviation is large. The reason is that the heating temperature is too high and the sodium acetate molecules undergo bimolecular decomposition to produce acetone. In order to remove by-products in the reaction C
