3-氯丙烯直接合成环氧氯丙烷催化剂研究进展
Research progress of catalyst for direct synthesis of epichlorohydrin from 3-chloropropylene
摘要
Abstract
The direct epoxidation of 3-chloropropene for synthesizing epichlorohydrin is a green chemical process,but highly relies on efficient epoxidation catalysts.The currently developed catalysts for epoxidation are predominantly homogeneous catalysts,such as phosphotungstate and metal complexes,and heterogeneous catalysts typified by titanium silicate molecular sieves.Among those homogeneous catalysts,phosphotungstate demonstrate superior reactivity due to their phase-transfer characteristics.This paper offers an overview on the synthesis of phosphotungstate catalysts and their current application in epoxidation processes.Regarding heterogeneous catalysts,the paper summarizes the reaction mechanism and progress in catalyst modification of titanium silicate molecular sieves for the epoxidation of 3-chloropropene.The application status of this catalyst in the epoxidation process is analyzed,and recommendations are given for further catalyst research in an industrial context.Additionally,a direct epoxidation scheme for 3-chloropropene employing molecular oxygen as the oxidant is discussed.Dual-functional catalysts suitable for this reaction should be developed to reduce the production costs of the direct epoxidation process for 3-chloropropene.关键词
