Abstract
Continuous flow reactors exhibit unique advantages in the synthesis of fine chemicals, addressing the limitations of traditional batch reactors such as low mass and heat transfer efficiency and significant scale-up effects. Continuous flow reactors offer efficient mass and heat transfer, precise control of reaction conditions, and ease of automation. This study aims to design and optimize continuous flow reactors for fine chemical synthesis to enhance product yield and quality while reducing costs. By integrating theoretical analysis with experimental research, a mathematical model was first established based on chemical reaction kinetics principles to determine the impact mechanisms of key factors such as flow rate, temperature, and pressure on the reaction process. Computational fluid dynamics software was then utilized to simulate flow field distributions under different structural parameters, providing a basis for physical structure design. Subsequently, response surface methodology was employed to optimize combinations of operating parameters, upon which an experimental setup was constructed for validation experiments. The results indicate that the designed continuous flow reactor significantly improves the reaction environment, increasing target product yield by 30% compared to traditional methods, reducing by-product formation by 25%, and enhancing product quality stability. This research innovatively integrates multidisciplinary knowledge into the design and optimization of continuous flow reactors, offering new approaches and technical means for fine chemical synthesis, thereby promoting technological advancement in related fields.
