连续催化氧化工艺在精细化学品合成中的应用
摘 要
Abstract
As an important technical means in the field of fine chemicals synthesis, the continuous catalytic oxidation process has shown significant advantages in improving the reaction efficiency and selectivity in recent years. In this study, the problems of low conversion rate and many by-products discussed the potential of continuous catalytic oxidation process in the synthesis of fine chemicals. By designing a new microchannel reactor and optimizing the catalyst loading mode, an efficient and stable continuous catalytic oxidation system was established. The experimental results show that the process can increase the selectivity of the target product to more than 95%, and shorten the reaction time to 1 / 3 of the conventional process. Research has innovatively developed multifunctional catalysts based on transition me tal complexes to achieve efficient oxidative conversion under mild conditions. The synthesis of typical compounds such as benzyl alcohol and cyclohexanone confirmed that the process has excellent universality and stability. Economic analysis shows that the continuous catalytic oxidation process can reduce energy consumption by 30% and reduce waste discharge by 40%.
