Abstract
This review presents a comprehensive description of the current pathways used in the chemical recycling of oxygenated plastics, with a specific focus on poly(ethylene terephthalate) (PET), poly(bisphenol-A carbonate) (PC), and polyethers including anhydride-cured epoxies. For PC and PET, the emphasis is on processes that achieve high depolymerization efficiencies as well as monomer selectivity and the potential to simplify downstream processing for the recovery of pure monomers. In the case of epoxies, this work focuses on depolymerization processes that produce curable molecules, as studies on epoxy depolymerization are scarce. To assess scalability, different depolymerization pathways are compared for each polymer based on the process conditions and monomer yields. The review concludes with the discussion on potentials and challenges of the distinct depolymerization pathways that have been developed for oxygenated plastics, such as hydrolysis, alcoholysis, and reductive depolymerization.
本综述全面介绍了当前含氧塑料化学回收利用的途径,特别关注聚对苯二甲酸乙二酯(PET)、聚碳酸双酚 A(PC)和聚醚(包括酸酐固化环氧树脂)。对于 PC 和 PET 来说,重点是实现高解聚效率和单体选择性的工艺,以及简化下游加工以回收纯单体的潜力。至于环氧树脂,由于有关环氧树脂解聚的研究很少,因此这项工作的重点是能产生可固化分子的解聚工艺。为了评估可扩展性,根据工艺条件和单体产量,对每种聚合物的不同解聚途径进行了比较。综述最后讨论了针对含氧塑料开发的不同解聚途径(如水解、醇解和还原解聚)的潜力和挑战。
