3-Bromophenol is working when is the right amount of bromine . If overdose is easy to react . But the resulting product is not tetrabromo phenol . But on the position of two phenolic hydroxyl bromine , has destroyed the conjugate structure of benzene . The color is pale yellow precipitate . If this happens , you can add potassium iodide to the reduction, to be Tribromophenol .
Health hazards : toxic manifestations of increased respiratory rate , breathing deeply , body tremors and sometimes convulsions and even death , can cause significant lung disease from mild to severe congestion and spotting , by mouth of the gastrointestinal tract irritation and corrosion .
Acute toxicity : LD50200mg/kg ( rat oral )
1.Hazardous characteristics : high fever by the decomposition of toxic gas bromide .
2.Combustion ( decomposition ) products : carbon monoxide , carbon dioxide, bromide .
3 .Emergency Monitoring Methods
4 .Laboratory monitoring methods
Uses : Preparation for disinfection antiseptic drug tribromophenol bismuth . Tribromophenol available aqueous solution polycondensation method or precipitation polymerization method as poly 2,6 – bromophenyl ether . This is a newly developed flame retardant , can be used for nylon 66 , thermoplastic polyester and modified polyphenylene ether and other engineering plastics can also be used for high impact polystyrene , ABS resin .
