废聚酯的循环利用

Recycling of Used Polytethylene Terephalate

废聚酯可通过化学解聚等手段来实现其循环利用。阐述了废聚酯循环利用领域的研究现状。介绍了目前国内外开发的废聚酯循环利用工艺方法 ,其主要方法有水解法、甲醇解聚法、乙二醇解聚法等。

Used poly(ethylene terephalate)(PET) can be recyclized by chemical depolymerization.The state of the art of chemical recycling of PET polyester was reviewed and several methods for chemical recycling such as hydrolysis,methanolysis,glycolysis and so on were introduced.
