碱金属醇解聚聚对苯二甲酸乙二醇酯(PET)在常温下被碳酸二甲酯(DMC)捕获乙二醇(EG)而有效地催化了甲醇分解，由于碳酸乙二酯(EC)的热稳定性使平衡偏向于对苯二甲酸二甲酯(DMT)。
Depolymerisation of polyethylene terephthalate (PET) via alkali metal alkoxide catalysed methanolysis efficiently proceeded at ambient temperature by capturing ethylene glycol (EG) with dimethyl carbonate (DMC), which biased the equilibrium toward dimethyl terephthalate (DMT) due to the thermal stability of ethylene carbonate (EC).
