摘要： 连续反应是物理化学动力学教学中的核心内容，其数学处理相对复杂，常导致学生对其理解仅停留在公式层面，难以与实际科研问题相联系。本文从科教融汇的理念出发，系统阐述了典型一级连续反应的动力学特征，并深入探讨了如何利用动力学方程解析反应决速步、优化目标产物产率及推导反应机理。通过引入苯氧化制苯酚、苯酚加氢制环己酮、苯甲醇氧化制苯甲醛及苯甲醛一步法制苯甲腈四个前沿科研案例，展示了如何将抽象的连续反应动力学方程转化为分析复杂反应体系、解释实验现象和指导催化剂设计的有效工具，为物理化学教学提供了生动的科研素材，架起理论与实践的桥梁，培养学生的科学思维与创新能力。

Abstract: Consecutive reactions are a core topic in physical chemistry kinetics. Their complex mathematical treatment often leads students to merely memorize formulas without connecting them to realworld research problems. From the perspective of education–research integration, this paper systematically elaborates on the kinetic characteristics of typical first-order consecutive reactions. It further explores how to apply the corresponding kinetic equations to identify rate-determining steps, optimize the yield of target products, and elucidate reaction mechanisms. By introducing four cutting-edge research cases—selective oxidation of benzene to phenol, hydrogenation of phenol to cyclohexanone, oxidation of benzyl alcohol to benzaldehyde, and one-pot synthesis of benzonitrile from benzyl alcohol—this paper demonstrates how abstract kinetic equations can be transformed into powerful tools for analyzing complex reaction systems, interpreting experimental phenomena, and guiding catalyst design. This work aims to provide vivid research material for physical chemistry teaching, bridge the gap between theory and practice, and cultivate students’ scientific thinking and innovative capabilities.
