    摘要: A method for producing bisphenol includes introducing a phenol and a ketone into a fixed, supported catalytic bed reactor system in a downflow mode, reacting the phenol and the ketone to form a reaction mixture, and recovering the bisphenol isomer from the reaction mixture. The preferred bisphenol isomer is bisphenol A, or p,p′-bisphenol A, produced from the reaction of phenol and acetone. The reactor for producing the bisphenol A from the reaction of phenol and acetone includes an ion exchange resin catalyst disposed in a bed and packing randomly distributed throughout the ion exchange resin catalyst to improve heat transfer efficiency and reduce compression of the catalyst bed.

    摘要: This invention relates to a method of recovering a polymer from an organic mixture comprising polymer and an organic solvent, the method comprising: a) admixing an aqueous solution and the organic mixture by the application of a combined mechanical and hydraulic shear force, the combined mechanical and shear force being sufficient to form a liquid-liquid dispersion; b) removing the organic solvent from the liquid-liquid dispersion thereby forming a remaining solution; and c) separating the polymer from the remaining solution. In one embodiment the polymer is a polycarbonate prepared by the interfacial method, and the organic solvent is methylene chloride.
