摘　　要：文章详细阐述了由海盐制备试剂级氯化钠的过程和方法,分析了实验过程中遇到的问题以及解决问题的方法,帮助学生分析海盐成分并设计实验如何将海盐中可溶盐除去,还需要让学生了解产品的检验方法和对比分析问题的能力,同时强调操作中的注意事项以及实验室的安全注意事项。通过实验过程紧密联系实际,及时进行课程思政教育,培养学生绿色化学的理念。In this paper, the process and method of preparing reagent-grade sodium chloride from sea salt are described in detail, to help students analyze sea salt and design experiments to remove the soluble salt in sea salt, students need to understand the product testing methods and the ability to compare and analyze problems. At the same time, the attention of operation and the safety of the laboratory should be emphasized. Through the experiment process close contact with the reality, carries on the curriculum ideological and political education in time, trains the student the green chemistry idea.
