Poly(ethylene terephthalate) (PET) is one of the most commonly used plastics for a wide range of applications, but is also one on the main contributors to the accumulation of plastic waste in the environment. Herein, we propose an aminolytic method to depolymerise PET using various amino-alcohols by organocatalysis and their subsequent use for the production of poly(ester-amide)s. This research aims to highlight the potential of thermally stable acid–base mixtures for depolymerization of PET in the presence of amines, specifically TBD : MSA. The chemoselectivity of the process favors the formation of diol terephthalamides in high yields. Different amino alcohols are also explored in order to obtain diols with secondary amine or ether functionalities. Finally, these novel terephthalamide diols are investigated as novel synthons for the synthesis of poly(ester-amide)s, showing potential for the “creative reuse” of plastic wastes.

使用热稳定的有机催化剂对聚对苯二甲酸乙二酯废料进行氨解上链

聚对苯二甲酸乙二酯（PET）是广泛应用的最常用的塑料之一，但也是造成环境中塑料废物积累的主要因素之一。在本文中，我们提出了一种氨解方法，该方法使用各种氨基醇通过有机催化使PET解聚，并将其随后用于生产聚（酯-酰胺）。这项研究旨在强调在胺（尤其是TBD：MSA）存在下，热稳定的酸碱混合物在PET解聚中的潜力。该方法的化学选择性有利于高产率地形成二醇对苯二甲酰胺。为了获得具有仲胺或醚官能度的二醇，还探索了不同的氨基醇。最后，
