Tris (tribromophenoxy) - s -triazine ( TTBP-TAZ ) is an organic chemical compound belonging to the triazine group .
Extraction and presentation
The illustration comprises the reaction of an aqueous solution of 2,4,6-tribromophenolate with cyanuric chloride in the presence of a phase transfer catalyst .
use
Tris (tribromophenoxy) - s -triazine is used as a flame retardant . We recommend using it with polyethylene films and pipes. It was found in plastic parts of new electrical appliances, but was missing from old ones. In the electrical an average concentrations of 14 ± 5 was in a 2011 study, ppm found that the occurrence of TTBP-TAZ confirmed in electronic devices.
