Abstract
The optimization and improvement of fine chemical synthesis processes represent a critical direction in the development of modern chemical industry. As market demands become increasingly diverse and environmental requirements continue to rise, traditional synthesis methods face numerous challenges. This study addresses issues such as low reaction efficiency, poor selectivity, and excessive by-products in current fine chemical synthesis processes. Using representative fine chemicals as research subjects, this work combines theoretical calculations with experimental studies to systematically optimize the synthesis process through the introduction of novel catalysts, optimization of reaction conditions, and enhancement of separation and purification techniques. In the area of new catalysts, high-activity and high-selectivity catalysts were screened and designed, significantly improving the yield of target products. For reaction condition optimization, response surface methodology was employed to determine optimal combinations of temperature, pressure, solvent systems, and reaction time, making the reaction process milder and more controllable. In terms of separation and purification, an innovative method combining high-performance liquid chromatography with crystallization was developed, effectively reducing production costs and minimizing environmental pollution. The results demonstrate that these comprehensive optimization measures not only enhance product quality but also substantially reduce energy consumption and waste emissions, providing crucial technical support for achieving green and sustainable development in the fine chemical industry. The innovation lies in integrating multiple advanced technologies and concepts into practical production process improvements, offering valuable experience for the process optimization of similar products..
