Abstract
Fine chemicals play an indispensable role in modern industry and daily life, and the optimization of their synthesis and processes is crucial for improving product quality, reducing costs, and enhancing competitiveness. This study focuses on exploring synthetic pathways and optimizing process parameters for a specific fine chemical, aiming to develop efficient, green, and economically viable synthetic methods. By systematically analyzing the advantages and disadvantages of existing synthetic routes and employing quantum chemistry calculations to predict reactive sites, a novel synthetic system utilizing green solvents as media and transition me tals as catalysts was selected. The response surface methodology was adopted to optimize key process parameters such as temperature, pressure, and catalyst dosage, establishing mathematical models to guide practical production operations. The results indicate that under optimized conditions, the yield of the target product significantly increased to 92.5%, while by-product formation was substantially reduced, and waste emissions decreased by more than 30%. This research innovatively incorporates quantum chemistry-assisted design concepts, achieving effective integration from molecular-level understanding of reaction mechanisms to macroscopic process control, providing theoretical basis and technical support for the green synthesis of similar products, and possessing significant academic value and promising application prospects.
