2025-11-28 Data on methanolysis of polycarbonate and recovery and separation of bisphenol A doi:10.57760/sciencedb.j00124.00311 en Polycarbonate particles with a molecular weight of 45000 were used in the experiment. The depolymerization reaction was carried out in a high-pressure reactor at 160 °C and nitrogen atmosphere for 8 hours. The depolymerization products were qualitatively and quantitatively analyzed by gas chromatography-mass spectrometry ( GC-MS ).  The peak area of the depolymerization product was averaged three times, and the quality of the product was obtained by bringing in the standard curve of each product, and the Origin drawing was used.  The recovered BPA was detected by GC-MC and NMR instruments, and its purity was detected by comparison with commercial BPA. polycarbonate; methanolysis; bisphenol A; catalysts-free; chemical recycling.
