按照化学课本进行甲烷制备实验,存在着这样一些客观问题:如产生的甲烷气体量很少,点不着或火苗很小,课堂演示效果不理想,加热反应不久,装反应物的试管往往出现炸裂现象;有时即使试管没有炸裂,但反应之后很难清洗干净,不能作其它实验用。由于这些原因,许多人从不同的角度进行了探索和研究,本文拟从以下几方面作一些探索。 According to the chemistry textbook for methane preparation experiments, there are some objective problems: if the amount of methane gas produced is small, the ignition point is not or the flame is small, the classroom demonstration effect is not ideal, the heating reaction is short, and the test tubes containing the reactants often burst. Sometimes even if the test tube does not burst, it is difficult to clean after the reaction and cannot be used for other experiments. For these reasons, many people have explored and studied from different perspectives. This article intends to make some explorations from the following aspects.
