Bis 4-chlorophenyl sulfone
WebThe dynamics of organohalogen contaminants and their metabolites are best studied over time by analysis of biota at high trophic levels. In this study, time trends, 1971-2001, of bis(4-chlorophenyl) sulfone (BCPS) and of methylsulfonyl-substituted metabolites of PCBs and 4,4'-DDE, were investigated in eggs of guillemot (Uria aalge) hatching in the Baltic … WebAdditionally bis (4-chlorophenyl)-sulfone and linear alkylbenzenesulfonates (LAS) were detected in marine waters. Proof of identification is given by comparison of spectral and chromatographic data from the compounds in sample extracts to those obtained from pure standards. In extracts obtained from water samples taken in 1990 and 1995 the ...

The simplest polysulfone poly(phenylene sulfone), known as early as 1960, is produced in a Friedel-Crafts reaction from benzenesulfonyl chloride: n C6H5SO2Cl → (C6H4SO2)n + n HCl With a melting point over 500 °C, the product is difficult to process. It exhibits attractive heat resistance, but its mechanical properties are rather poor. Polya… WebJan 1, 2024 · Bis(4-chlorophenyl) sulfone (BCPS, CAS No. 80-07-9) is used as monomer for the production of several groups of polymers like polysulphones and polyethersulphones. Residual amounts of monomer remain in the polymer matrix and might migrate out from the polymer matrix. In the present study, freshwater fish and fish-eating birds were examined.
