摘要

合成了通式为[Rmim]+MX3-（R=正丁基或正十二烷基；M=Zn，Cd；X=Cl，Br）的含金属离子液体，并用核磁共振光谱和红外光谱对其进行了表征。研究了聚对苯二甲酸乙二醇酯（PET）与乙二醇（EG）的糖酵解反应，主要产物为对苯二甲酸二-2-羟基乙酯（BHET）。以下参数是可变的：催化剂类型、催化剂负载量以及PET和EG之间的摩尔比。对于每个反应，计算转化率和选择性。所有这些反应在所需产物中以高选择性产生，PET的转化率为准全。

Metal-containing Ionic Liquids as Catalyst in PET Glycolysis

Metal-containing ionic liquids with general formula [Rmim]+MX3- (R=n-butyl or n-lauryl; M=Zn, Cd; X=Cl, Br) were synthesised and then characterized by nuclear magnetic resonance spectroscopy and infrared spectroscopy. The catalytic activity was tested in glycolysis of poly(ethylene terephthalate) (PET) with ethylene glycol (EG) with the main product being bis-2-hydroxyethyl terephthalate (BHET). The following parameters were varied: the catalyst type, the catalyst loading and the molar ratio between PET and EG. For every reaction conversion and selectivity were calculated. All these reactions arose with high selectivity in the desired product, the conversion of PET being quasi-total.
