Abstract: Propylene Oxide is a significant organic chemical material with extensive applications across various industries. This paper primarily introduces two traditional production processes for PO, thoroughly analyzes the safety risks during its production process, and proposes corresponding safety measures to ensure the safety and stability of the production process. By optimizing process control, upgrading equipment materials, and strengthening safety interlock systems, risks such as fire explosion, equipment corrosion, and environmental pollution during production process can be effectively mitigated. This study provides theoretical support and technical guidance for the safe production of PO.

Key words: propylene oxide, chlorohydrin method, co-oxidation method, safety analysis
