    摘要: The invention relates to a process for obtaining 4,4'-dichlorodiphenyl sulfoxide from a liquid mixture comprising 4,4'-dichlorodiphenyl sulfoxide and a solvent, comprising: (a) cooling the liquid mixture to a temperature below the saturation point of 4,4'-dichlorodiphenyl sulfoxide in the solvent to obtain a suspension comprising crystallized 4,4'-dichlorodiphenyl sulfoxide, (b) solid-liquid-separation of the suspension to obtain a residual moisture containing solid 4,4'-dichlorodiphenyl sulfoxide as a product and mother liquor, (c) concentrating the mother liquor, (d) recycling at least a part of the concentrated mother liquor into the cooling step (a).

    摘要: A process for preparing diaryl sulfones, such as 4,4'-dichlorodiphenylsulfone is disclosed. The process comprises contacting an aryl compound with sulfur trioxide to provide a benzene sulfonic acid. The benzene sulfonic acid is coupled to additional aryl compound in the presence of a catalyst. During the coupling step, the additional aryl compound is continuously added while water is removed.
