    摘要: A process for the preparation of dihalodiphenylsulfones_such as 4,4′-dichlorodiphenyl sulfone or 4,4′-bis-(4-chlorophenylsulfonyl)biphenyl with high regioselectivity, at low temperature and in the absence of toxic reagents by reacting together at least one acid, sulfur trioxide and at least one halobenzene. The invented process is particularly suited for the manufacture of 4,4′-dichlorodiphenyl sulfone.

    摘要: The present invention describes a process for preparing a poly(aryl ether ketone) by reacting a nucleophile with 4,4′-difluorobenzophenone (4,4′-DFBP) that is improved through the use of 4,4′-DFBP that meets one or more particular purity conditions. Also described are improved poly(aryl ether ketone) produced using the invention 4,4′-DFBP. Amounts of 2,4′-difluorobenzophenone (2,4′-DFBP), 4-monofluorobenzophenone (4-FBP), chlorine, and monochloromonofluorobenzophenone in 4,4′-DFBP are discussed.
