甲烷实验室制法的改进

Improvement of the Methods to Prepare Methane in the Laboratory

采用醋酸钙与氢氧化钙（成氢氧化钡）和氧化钙制备甲烷，实验成功率高，产生的甲烷气体多，操作方便，且不腐蚀 试管，是一种实验制备甲烷的有效方法。

Metheane can be prepared with calcium acetate and Ca(OH)2(or Ba(OH)2) in the laboratory.The method is successful and convenient. It doesn' t corrode tubes, and is one of effective methods to prepare methane in the laboratory.
