2-Ethylhexyl-2,3,4,5-tetrabromobenzoate ( EH-TBB or TBB ) is a flame retardant and is one of the organic - chemical compounds .

properties

Structural formulas of the two enantiomers

EH-TBB is the ester of tetrabromobenzoic acid and ( racemic ) 2-ethylhexanol . The compound is accordingly present as a racemate of two enantiomers .

use

EH-TBB and bis (2-ethylhexyl) tetrabromophthalate (BEH-TEBP) are the two brominated components of the commercial flame retardant mixture Firemaster 550 , which together make up around 50 percent by mass, with a mass ratio of 4: 1. The remaining 50 percent by mass consists of an isopropylated triaryl phosphate and a triphenyl phosphate. Firemaster 550 is used as a flame retardant on plastics such as polyurethane . In electronic waste an average concentration of 4 was in a 2011 study conducted ppm found what the occurrence of EH-TBB confirmed in electronic devices.

proof

The EU recommends that its member states monitor foodstuffs for traces of EH-TBB and other brominated flame retardants.
