摘　　要：“二草酸合酮酸钾的制备”是一个经典的无机化学实验,通过该实验可以进一步提高学生的称量、水浴加热、蒸发浓缩、结晶、减压过滤等基本操作技能。但原实验方案中是以重新制得的氢氧化铜经热解得到的氧化铜为原料,存在资源浪费、环境污染和产物形貌难以控制等问题。本文从绿色化学的理念出发,对该实验进行了改进。一方面创新性地使用前期回收的氢氧化铜为原料,实现了资源的有效利用;另一方面通过对反应液体积和冷却条件的简单控制,方便地实现了对产物形貌的调控。同时将显微镜引入用于观察产物的形貌,不仅提高了实验的趣味性,还可进一步引导学生对影响产物形貌的原因进行探究。改进后的实验方案和实验内容不仅提高了资源利用率,降低了污染,提升了学生的绿色合成理念,且更有助于培养学生的科研素养。Preparation of potassium bis(oxalato)cuprate(II)is a classical inorganic chemistry experiment that helps students refine essential skills such as weighing,water-bath heating,evaporation-crystallization,and vacuum filtration.However,in the traditional experimental scheme,copper oxide obtained from the pyrolysis of copper hydroxide is used as raw material,which leads to waste of resources,environmental pollution and challenges in controlling the product morphology.This study introduces improvements based on green chemistry.Firstly,previously recovered copper hydroxide was innovatively used as the raw material,enhancing resource utilization.Secondly,simple adjustments to the reaction liquid volume and cooling conditions were employed to conveniently control morphology.Simultaneously,microscope was also introduced to observe the product morphology,enhancing the experiment’s engagement and guiding students in exploring factors affecting morphology.The improved experimental procedure not only boosts resource efficiency and reduces pollution,but also promotes the concept of green synthesis and cultivates students’scientific research literacy.
