| 摘 要： | 研究了溴乙烷消去反应发生的条件,结果表明：溴乙烷与饱和KOH乙醇溶液的混合液温度低于80℃时,绝大部分发生取代反应生成乙醚,温度高于80℃时开始生成乙烯的消去反应加快,发生消去反应的演示实验的最佳反应条件是：温度为95℃;溴乙烷与饱和KOH乙醇溶液的体积比是1∶3。

| Abstract: | The conditions of elimination reaction of bromoethane is investigated.The result shows that when the temperature of the mixed solution of bromoethane and saturated KOH ethanol is below 80℃,ether is the main products because of substitution reaction.And when the temperature is higher than 80℃,the elimination reaction appears to be dominant and the optimal conditions of elimination reaction are as follows：the temperature is up to 95℃ and the volume ratio between bromoethane and saturated KOH ethanol solution is 1∶3. |
