Facile synthesis of diarylsulfones from arenes and 3CdSO4·xH2O via mechanochemistry

A variety of substituted diarylsulfones could be synthesized by simple arenes and 3CdSO4·xH2O in the presence of P2O5 under high-speed ball milling. It was suggest the aromatic sulfonation was performed by arene and in situ generated H2SO4, following-up by electrophilic substitution with another arene to give diarylsulfone.

Thermal recording material

A thermal recording material having both of excellent coloring property and storage stability with a low cost is provided. The thermal recording material contains a leuco dye and a developer in a coloring layer, and the developer contains 2,4′-dihydroxydiphenylsulfone and 4,4′-dihydroxydiphenylsulfone with a specific ratio, and the above-mentioned two kinds of the dihydroxydiphenylsulfones are made a material obtained by sequentially undergoing a separating step for heightening the weight ratio of a 2,4′ material from a dichlorodiphenylsulfone mixture containing the 2,4′ material and a 4,4′ material, a reaction step of hydrolyzing the mixture to obtain a dihydroxydiphenylsulfone mixture, and a post-treatment step of subjecting to decolorization and purification.

PROCESS FOR PREPARING 4,4'-DICHLORODIPHENYL SULFONE

The invention relates to a process for preparing 4,4′-dichlorodiphenyl sulfone, comprising the reaction of monochlorobenzene and liquid sulfur trioxide, wherein the liquid sulfur trioxide used has a boron content of at most 100 ppm based on the total weight of the sulfur trioxide used, including all secondary components.
