  • Process for continuously producing monomer components from aromatic polyester
    Patent number: 6262294
    Abstract: This invention relates to a process for producing aromatic divalent carboxylic acid ester and diatomic alcohol by reacting aromatic polyester and super critical monatomic alcohol, and by the process, PET is decomposed for recovering monomer components therefrom, and thus recovered monomer components can be used as the material for reproduction of new PET. In accordance with the present invention, there is provided a process for producing continuously monomer components from aromatic polyester, the process including the steps of: feeding continuously the above aromatic polyester and the above monatomic alcohol into a reactor while the above reactor is kept to be under the super critical condition of the above monatomic alcohol; reacting the above aromatic polyester and the above super critical monatomic alcohol and discharging the resultant reaction products, i.e.
