%X 聚对苯二甲酸乙二醇酯(PET)因其具有透明度高、重量轻和无毒等特性，广泛应用于饮料瓶、纺织品、塑料薄膜和食品包装等领域。随着PET的生产和消费快速增长，大量废弃PET造成的环境污染问题日益突出。本文概述了PET化学解聚为高附加值化学品的方法，主要包括水解法﹑醇解法﹑糖解法、胺解法和氢解法，同时讨论了不同化学解聚方法的优缺点，并对未来PET升级回收进行了展望。<br />
Polyethylene terephthalate (PET) is widely used in beverage bottles, textiles, plastic films, and food packaging due to its high transparency, light weight, and non-toxic properties. With the rapid growth of PET production and consumption, the environmental pollution caused by a large amount of waste PET has become increasingly prominent. In this paper, the methods of chemical depolymerization of PET into high value-added chemicals are summarized, including hydrolysis, methanolysis, glycolysis, aminolysis and hydrogenolysis. The advantages and disadvantages of different chemical depolymerization methods are discussed, and the future upgrading and recycling of PET are prospected.
