配合物[Ni(Me3en)(acac)]BPh4合成、分析实验实施结果与讨论——第10届全国大学生化学实验邀请赛无机及分析化学实验试题部分内容实施结果与讨论
摘要:
介绍南京大学为第10届全国大学生化学实验邀请赛设计的无机及分析化学实验试题，即“配合物[Ni(Me3en)(acac)]BPh4的合成及其溶剂/热致变色行为研究”实验中有关合成及组成测定部分实验实施过程、结果及其拓展问题的探讨内容。以所展示的详细直观的合成实验流程为载体，围绕着合成两大目标“质”和“量”，即如何才能得到又“好”又“多”的[Ni(Me3en)(acac)]BPh4配合物的问题为导向，以设问、探讨的方式引导学生认识合成过程中实验条件的控制、实验现象的分析以及中间产物及杂质的分离、分析鉴定等对指导合成的意义，培养学生分析、判断、归纳、总结的能力以及批判性思维能力。

Results and Discussion on the Synthesis and Analysis of [Ni(Me3en)(acac)]BPh4 Complex: The Results and Discussion of Inorganic and Analytical Chemistry Experiment of the 10th National Undergraduate Chemistry Laboratory Tournament
Abstract:
This paper mainly introduces the experiment implementation process, results and extension issues in the synthesis and composition determination part of the inorganic and analytical chemistry laboratory project, the synthesis of the complex [Ni(Me3en)(acac)]BPh4 and its solvato/thermochromic behavior research experiment, designed by Nanjing University for the 10th National Undergraduate Chemistry Laboratory Tournament. Based on the detailed and intuitive synthetic experimental process shown, we focus on the two major goals of synthesis, the “quality” and the “quantity”, i.e., guided by how to obtain both “good” and “more” [Ni(Me3en)(acac)]BPh4 complex. By asking questions and discussing, we instruct students to understand the experimental process. Through the above process, the students are guided to understand the significance of the control of experimental conditions, the analysis of experimental phenomena and the separation, analysis and identification of intermediate products and impurities in the process of synthesis. As a result, students can develop the ability of analysis, judgment, induction, summarizing and critical thinking.
