摘　　要：以绿色化学的理念,在传统实验中引入新技术、新方法,将经典的"苯甲醛Cannizzaro反应制备苯甲酸和苯甲醇"实验改进为一个结合了超声波/相转移催化、反应过程紫外光谱监测和产物核磁表征分析的探索性综合实验,充分发挥学生的主观能动性,既激发了学生的学习积极性,又培养了学生的创新思维和研究能力,获得了良好的实验教学效果.Based on the concept of green chemistry, new technologies and methods are introduced into traditional experiments, and the classical experiment of “Cannizzaro reaction to prepare benzoic acid and benzyl alcohol” is improved into an exploratory comprehensive experiment which combines together the ultrasonic/phase transfer catalysis, ultraviolet spectroscopy monitoring of reaction process and NMR characterization analysis of products, giving full play to students’ subjective initiative, which not only stimulates their learning enthusiasm, but also trains their innovative thinking and research ability. It has achieved good experimental teaching effect.
