To address the high risks and insufficient dynamic process visualization associated with traditional thermal safety experiments for chemical reactors in the courses on chemical process thermal risk assessment and chemical equipment safety technology, this paper designs a simulation-based teaching plan for chemical reaction thermal safety. Taking a semi-batch reactor for the ammoximation reaction of cyclohexanone as the example, steady-state and dynamic models were constructed to simulate the dynamic responses of thermal runaway under the of cooling water failure and fluctuations in reactant concentrations. Dynamic simulation was utilized to achieve real-time tracking of process parameters, revealing the mechanisms of thermal runaway and defining safe operating boundaries of the reactors. This teaching plan integrates knowledge from chemical thermodynamics, reaction engineering, and process control, leveraging virtual simulation technology to overcome the limitations of traditional experiments, thereby cultivating students’ engineering practice abilities and innovative thinking. Practical application has demonstrated that this experiment enhances students’ understanding of the mechanisms behind reaction thermal runaway, strengthens the integration of theory and engineering application, and provides a new paradigm for experimental teaching in chemical safety. %K 化工安全， %K 热失控， %K 反应器， %K 热安全， %K 教学设计， %K 动态模拟
