油脂环氧化工艺及装备的研究进展
Research progress in process and equipment of oil epoxidation
摘要
Abstract
Natural vegetable oils and their derivatives are renewable resources that serve as raw materials for epoxidation reaction.The resulting epoxy products are essential platform chemicals widely used in PVC plastics and the production of various bio-based materials.In industry,the epoxidation is commonly conducted in a batch stirred reactor by Prileschajew method,which is a liquid-liquid reaction system with highly exothermic.The large liquid holdup,high risk of flying temperature,and low product quality are the bottleneck issues throughout the reaction process.Therefore,designing efficient reaction processes and developing advanced intensification equipment have become key areas demanding urgent innovative research,playing a significant role in enhancing product quality and process safety.Accordingly,the epoxidation methods for preparing epoxy products with various catalysts are reviewed,highlighting the development and catalytic properties of each catalyst.Secondly,kinetic modeling approaches for Prileschajew epoxidation are presented,introducing the modeling principles,key processes,advantages and limitations of each method.Furthermore,the mechanisms and effects of various process intensification equipment on epoxidation are outlined,analyzing the advantages in enhancing mass/heat transfer and intrinsic reaction.Finally,crucial challenges and future research directions are discussed,focusing on screening high-performance catalysts,designing efficient reaction processes,and developing intensification equipment.关键词
