WebMethanolysis of PET is a process in which the methanol reacts with PET to produce two main products: dimethyl terephthalate (DMT) and EG [7]. This mechanism usually runs … Web11 jun. 2024 · Methanolysis refers to the degradation of PET with methanol at high pressures and temperatures, producing dimethyl terephthalate (DMT) and ethlyene glycol (EG). This process is conducted at 180 to 280 °C and pressure of 2 to 4 MPa (Al-Sabagh et al. 2016). Catalyst is also used for this reaction, and the most common catalyst is zinc …
