摘　　要：离子液体具有独特的理化性质,是极具潜力的新型电解质。如何提高学生对离子液体电解质的学习兴趣和效率,特别是抽象概念和知识的学习,是当前化学教育新课题。以胍类离子液体(胍盐)中胍阳离子及其前驱体——胍的分析为例,提出了一种基于对问题多角度分析并引导学生联想学习的教学方案,旨在实现离子液体教学方法的多样化,使教学内容简明扼要以激发学生学习的兴趣。Ionic liquids are highly promising novel electrolytes with unique physicochemical properties.How to improve the efficiency and interests of students in learning ionic liquid electrolytes,especially abstract concepts and knowledge,is a topic of current chemical education.In this paper,a teaching scheme based on multi-angle analysis of problems and guiding students'associative learning is proposed,using the analysis of the guanidinium cation in guanidinium-based ionic liquids as well as its precursorguanidine as an example,aiming to diversify teaching methods for ionic liquids and simultaneously simplify the teaching content so as to stimulate students'interests in learning.
