中文摘要:
      综述了近些年国内外有关废旧聚酰胺(PA)类材料化学解聚的研究现状,重点介绍了几种主要的化学解聚方法,包括热降解、水解、氨解、酶解及超(亚)临界解聚等方法,并对各方法的应用现状进行了分析与总结。最后,对废PA在离子液体介质中的化学解聚行为进行了探讨,并指出离子液体环境下的化学解聚法有望成为处理废PA材料的一个重要研究方向。
英文摘要:
      In this paper, chemical depolymerization of waste polyamides was reviewed in recent years. Several methods of chemical depolymerization, including thermal degradation, hydrolysis, ammonolysis, enzymatic hydrolysis and supercritical (sub-supercritical) depolymerization, were summarized in detail, and the advantages and disadvantages of these methods were also analyzed. As reaction medium or catalysts, ionic liquids can be used for chemical depolymerization of PA to recover monomers or chemical products under mild reaction conditions. This method is expected to provide theoretical support in chemical recycling of waste polyamides, and will be an important research direction.
