摘 要:应用氯化钙与乙醇形成的结晶醇在加热条件下释放出乙醇的性质,作为乙醇氧化成乙醛实验中乙醇蒸气的固体载体,增加实验操作的方便性,同时节约了乙醇;将乙醛生成和检验实验同步进行,解决了演示实验时间长和教材实验依靠闻乙醛气味的不可靠性。This paper used crystallization alcohol formed by calcium chloride and ethanol as ethanol stream donor in experiment of ethanol oxidation into acetaldehyde,in which crystallization alcohol could provide ethanol stream under heating condition.The crystallization alcohol enhanced conveniences in experimental operation and saved the amount of alcohol.And the generation and test experiments of acetaldehyde were carried out concurrently,which saved the time and increased the reliability of acetaldehyde test.
