发明名称 ETHANOLYSIS OF PET TO FORM DET AND OXIDATION THEREOF
摘要 <p>A process for ethanolysis of PET is disclosed wherein a feed comprising PET is reacted with ethanol and recovering ethylene glycol and an aromatic diethyl ester such as diethyl isophthalate and/or diethyl terephthalate. PET, or a terpolymer comprising terephthalate monomer and ethylene glycol monomers, is reacted with ethanol and ethanol, diethyl terephthalate, ethylene glycol and optionally diethyl isophthalate are recovered. Recovered diethyl components can be subjected to liquid-phase oxidation to produce aromatic carboxylic acid. Acetic acid may also produced via liquid-phase oxidation of recovered diethyl components. The aromatic carboxylic acid can be used to form polymer.</p>
