摘要(Abstract)：

为探究铜锌催化剂结构对炔醛化反应合成1,4-丁炔二醇的影响，采用共沉淀法制备一系列铜锌催化剂，考察铜锌催化剂的焙烧温度、铜锌物质的量比、制备过程中沉淀剂的滴加方式等对催化剂结构及其对炔醛化反应的影响。结果表明，当铜锌物质的量比为2:1、采取沉淀剂正加方式、焙烧温度为450℃时制备的铜锌催化剂，体现最好的炔醛化反应活性。添加锌助剂后，铜锌催化剂中CuO颗粒尺寸减小、分散性增加，铜锌之间存在电子协同作用和氧空位是铜锌催化剂炔醛化活性与稳定性较高的主要原因。而铜化合物被过度还原为金属铜，影响催化剂活性与稳定性。

关键词(KeyWords)： 炔醛化反应;铜锌催化剂;焙烧温度;氧空位
