Abstract

Acid-, base-free depolymerization of poly(ethylene terephthalate) (PET) with ethanol catalyzed by FeCl₃, FeBr₃ (1.0–5.0 mol%) gave diethyl terephthalate (DET) and ethylene glycol (EG) exclusively (98–99%, 160–180 °C), and FeCl₃ showed better catalytic performance in terms of activity. The FeCl₃ catalyst enabled exclusive, selective depolymerization of PET from textile waste to afford DET (and recovered cotton waste), strongly suggesting the possibility of chemical recycling of cloth waste by the transesterification in this catalysis.

Keywords: Depolymerization; PET; Chemical recycling; Textile waste management; Homogeneous catalyst.

应用于布废料独家化学回收的均相铁催化剂用乙醇解聚 PET

用 FeCl3、FeBr3（1.0-5.0 mol%）对聚对苯二甲酸乙二醇酯（PET）与乙醇进行无酸、无碱解聚，只得到对苯二甲酸乙二醇酯（DET）和乙二醇（EG）（98->99 %，160-180 ºC），FeCl3 的催化剂活性表现更好。FeCl3 催化剂能使纺织废料中的 PET 独家进行选择性解聚，生成 DET（和回收的棉花废料），这有力地说明了在该催化反应中通过酯交换反应对纺织废料进行化学回收利用的可能性。
