Ft. Dettmer et al., Isolation and identification of tetrabromobisphenol-S-bis-(2,3-dibromopropyl ether) as flame retardant in polyporpylene, CHEMOSPHERE, 39(9), 1999, pp. 1523-1532
Approximately 4 % tetrabromobisphenol-S-bis-(2,3-dibromopropyl ether) and 0
.44 % antimony were found in the back wall of a TV cabinet. This is the fir
st time a bromoorganic flame retardant containing a sulfur linkage has been
detected. No such compound has been previously mentioned in the analytical
or environmental literature. Isolation from PP was performed by extraction
and precipitation of coextracted polymer. After chromatographic separation
(TLC, CC), the combination of (HC)-H-1-C-13-NMR, MS (EI), FT-IR and HPLC (
UV/Vis, DAD and MS) indicated the TBBP-S derivative, which was verified by
synthesis of reference material.
