    Abstract: The invention relates to a method for producing 4,4'-dihalogendiphenylsulfone by reacting halogenated benzene with 4-halogenphenylsulfonyl chloride in a liquid phase at high temperature, in the presence of a solid catalyst having acid centers. The method is characterized in that the reaction of 4halogenphenylsulfonyl chloride with formula (I), in which X is chlorine, bromine or fluorine, with chlorobenzene, bromobenzene, or fluorobenzene, is carried out in the presence of a catalyst which is selected from one of the following groups: K1) catalysts consisting of essentially stratified silicates not having Lewis acids and having proton-saturated negative layer loads, or containing these as a basic component; K2) catalysts consisting of zeolites in the acid H form, or containing these as a basic component; and K3) catalysts consisting of mixed oxides having acidic centres, or containing these as basic components. The mixed oxides consist of a combination of (a) titanium, circonium, hafnium, tin, iron or Cr(III) oxides on the one hand, and (b) vanadium, chromium(VI), molybdenum, wolfram or scandium oxides on the other hand; or the mixed oxides are sulfatized or phosphatized oxides of the group (a), and said mixed oxides are calcined after combination, at temperatures of 450 to 800 ~C.
