摘要
离子液体作为绿色介质,由于具有均相催化的特点,在催化聚对苯二甲酸乙二醇酯(PET)降解方面表现出优异的性能.近年来,本课题组开发了多个系列离子液体催化剂用于PET醇解.本文总结评述了本课题组及其他团队对于离子液体催化剂的研究进展,主要介绍了PET醇解催化剂,兼顾PET水解与胺解离子液体催化剂.详细阐述了催化剂及反应条件对转化率与收率的影响,总结了PET醇解动力学,并比较了不同离子液体催化剂的醇解活化能,同时归纳了离子液体催化剂的作用机理,以期为开发高效PET降解催化剂提供理论基础.
Ionic liquids as green media have shown excellent performance in catalyzing poly(ethylene terephthalate)(PET) degradation due to their homogeneous catalytic properties. Our group has developed several series of ionic liquid catalysts for PET glycolysis in recent years. This work summarizes and reviews the research progress of ionic liquid catalysts in our group and other teams. We focus on PET glycolysis catalysts, and also describe PET hydrolysis and aminolysis ionic liquid catalysts briefly. The effects of catalyst and reaction conditions on conversion and yield are detailed. The kinetic model of PET glycolysis and the activation energy for different catalysts are summarized. The mechanisms of ionic liquid catalysts are summarized to provide a theoretical basis for the development of efficient PET degradation catalysts.
