摘要:

有机过氧化物是一种常见的化工助剂,广泛被用作聚合引发剂、聚酯固化剂等。 传统间歇釜式过氧化工艺存在相间传递速率较低、工艺参数不易控和持液量大的问题,反应效率低且存在失控风险。 微化工系统比表面积大、传质传热速率快以及可控性高,在过氧化工艺中表现出一定优势。 本文从合成有机过氧酸、过氧酸酯、烷基过氧化氢和过氧化酮面临的共性与个性问题出发,综述了近10年内有机过氧化物在微反应器内合成的研究进展,介绍了微尺度下过氧化反应常用合成体系、工艺条件和反应器类型,分析了微反应器在提高过氧化工艺可控性、安全性和反应效率方面的重要作用及存在问题,最后提出解决思路并对发展趋势进行展望。

Abstract:

Organic peroxides are widely used chemical additives as polymerization initiators, polyester curing agents, crosslinking agents for polymer materials, and oxidants. The traditional synthesis process within batch reactor has low phase transfer rate, uncontrollable process parameters, large liquid hold-up, leading to low efficiency, poor quality, and high risk. Microreaction systems have unique advantages for peroxidation process due to their large specific surface area, enhanced mass and heat transfer rates, and high controllability. This article reviews the research progress on the synthesis of organic peroxides in microreactors in the past decadefrom the perspective of the general and specific challenges lying in the synthesis of organic peroxide acid, peroxyesters, alkyl hydroperoxide, and ketone peroxide. It introduces the commonly used reaction systems, operating parameters, and microreactor types for the synthesis of organic peroxides, discusses the important role and potential problems of microreactors in improving the controllability, efficiency, and safety in peroxidation reaction. Finally, the solutions and future development trends for the improvement of peroxidation in micro-scale are proposed.
