Heterogeneous Pd catalyst for oxidative carbonylation of bisphenol A to polycarbonate

Polycarbonates (PCs) were prepared by oxidative carbonylation of bisphenol A and carbon monoxide, using a Pd-polybipylidyl complex, Pd-polyvinylpyridine complex, smectite-supported Pd complex, or hydrotalcite-supported Pd complex as a heterogeneous Pd catalyst to separate the PC solution and the Pd...

Description
Summary:Polycarbonates (PCs) were prepared by oxidative carbonylation of bisphenol A and carbon monoxide, using a Pd-polybipylidyl complex, Pd-polyvinylpyridine complex, smectite-supported Pd complex, or hydrotalcite-supported Pd complex as a heterogeneous Pd catalyst to separate the PC solution and the Pd catalyst after the reaction. Propylene carbonate was used as a halogen-free solvent. When Co(OAc)₂·4H₂O was used as the inorgano-redox catalyst, all of the Pd compounds gave a good PC yield with the recycling potential of the catalyst.
