Abstract
Acid-base catalysts play an important role in the organic synthesis reaction, which can effectively reduce the reaction activation energy and improve the reaction rate and selectivity. The purpose of this study is to deeply explore the application and optimization of acid-base catalysts in organic synthesis reactions, systematically analyze the catalytic mechanism of different types of acid-base catalysts, and evaluate the influence of them on multiple typical organic reactions combined with experimental data. Using the method of combining theoretical calculation and experiment, Lewis acid, Brownsterian acid and solid acid were selected as the research ob jects to explore the reactions of olefin hydration, esterification and amidation in detail. The results show that different types of acid-base catalysts show unique catalytic properties under specific reaction conditions, in which the new heteropolyacid catalysts show significant advantages in improving the reaction yield and selectivity. By on the relationship between the structure and performance of the catalyst and regulating the acid strength are the key to improve the catalytic efficiency.
