    摘要： The present invention provides a method for the preparation of polymer grade 4,4'-dichlorodiphenyl sulfone in steps comprising reacting dimethyl sulfate and sulfur trioxide optionally containing a catalyst; reacting the formed dimethyl pyrosulfate with the unreacted sulfur trioxide optionally in the presence of a catalyst; reacting the reaction mixture with monochlorobenzene optionally containing a catalyst; optionally removing unreacted dimethyl sulfate; isolating crude 4,4'-dichlorodiphenyl sulfone using an organic solvent / organic solvent - water mixture; recovering the solvent from mother liquor; optionally recovering the isomeric mixture of dichlorodiphenyl sulfones from mother liquor; optionally, conversion of residual isomeric mixture of dichlorodiphenyl sulfones to a product selected from diphenyl sulfone, 2-aminodiphenyl sulfone; 2,4'-dihydroxydiphenyl sulfone, 4,4'-dihydroxydiphenyl sulfone; optionally recovering monochlorobenzene sulfonic acid and/or monochlorobenzene from the mother liquor; optionally recovering sulfuric acid from the residual liquor; optionally recycling the solvent; and purifying 4,4'-dichlorodiphenyl sulfone from crude followed by crystallization. Further the present invention discloses a process in which isomeric mixture of 4,4'-, 3,4'-, and 2,4'-dichlorodiphenyl sulfone produced during the preparation of 4,4'-dichlorodiphenyl sulfone is converted to value added products such as diphenyl sulfone, 2,4'-dihydroxydiphenyl sulfone, 4,4'-dihydroxydiphenyl sulfone and 2-aminodiphenyl sulfone.

    摘要： The present invention provides an economic and environmentally friendly method for the preparation of polymer grade 4,4'-dichlorodiphenyl sulfone which is substantially free of 2,4' and 3,4'-isomers of dichlorodiphenyl sulfone with yield of over 90%, with substantially reduced reaction times without the use of impregnated catalysts. Further no toxic byproducts such as dimethyl pyrosulfate are formed thereby reducing the load on effluent treatment with the added advantage of substantially recycling the reactants and byproducts. Further the present invention discloses a process is disclosed in which isomeric mixture of 4,4'-, 3,4'-, and 2,4'-dichlorodiphenyl sulfone produced during the preparation of 4,4'-dichlorodiphenyl sulfone is converted to value added products such as diphenyl sulfone, 2,4'- dihydroxydiphenyl sulfone, 4,4'-dihydroxydiphenyl sulfone and 2-aminodiphenyl sulfone.
