    摘要： The invention is directed to a method for manufacturing bisphenol A. The method for manufacturing bisphenol A comprises: a) reacting phenol and acetone in the presence of an acidic catalyst to form a reaction effluent, and b) crystallising p,p-bisphenol A from the reaction effluent so as to produce a crystal slurry, wherein reacting in step a) is performed in the presence of an inert co-solvent or wherein an inert co-solvent is added to the reaction effluent prior to crystallising in step b), and wherein the weight ratio between said inert co-solvent and said phenol during said crystallising is 60:40 or more.

    摘要： In the process for producing bisphenol A comprising crystallizing an adduct of bisphenol A and phenol from a phenol solution of bisphenol A obtained by reacting phenol and acetone in the presence of an acid catalyst, treating the formed slurry by solid-liquid separation and removing phenol from the solid component, a layer of the crystalline adduct is formed on a filter by filtering slurry (1) comprising the crystalline adduct, washing the layer of the adduct with a washing liquid, dissolving the layer of the adduct in a solution comprising phenol, producing slurry (2) comprising the crystalline adduct by crystallization, and separating the crystalline adduct by centrifugation of slurry (2). When bisphenol A is separated from the reaction mixture, the adduct of bisphenol A and phenol can be recovered from the mother liquor of the reaction efficiently at a high purity in accordance with the above process.

    摘要： A method for preparing and isolating dihydroxybiaryl compounds, such as 4,4′-dihydroxybiphenyl, is disclosed. The alkali metal salt of the dihydroxybiaryl compound is protonated with the monohydroxyaryl halide compound initially used in the reductive coupling reaction which produced the alkali metal salt. In addition, the alkali metal salt of the monohydroxyaryl halide compound is produced by the process, which can then be recycled as the base and monohydroxyaryl halide in a further reductive coupling reaction to form the alkali metal salt of the dihydroxybiaryl compound.
