Decabromodiphenyl oxide химические свойства, назначение, производство
Химические свойства
Decabromodiphenyl Oxide (DBDPO) is a white to off-white or light yellow powder. Almost insoluble in all solvents. Good thermal stability. Heated to 354 ℃, weight loss 5%. It is a non-toxic and non-polluting flame retardant.
Определение
ChEBI: Decabromodiphenyl ether is a polybromodiphenyl ether that is diphenyl ether in which all of the hydrogens have been replaced by bromines. It has a role as a neurotoxin.
прикладной
Decabromodiphenyl oxide is an unreactive, additive flame retardant widely used for its thermal stability and its low cost in thermoplastic resins, thermoset resins, textiles and adhesives. The major applications are in high impact polystyrene, glass reinforced thermoplastic polyester and moulding resins, low density polyethylene extrusion coatings, polypropylene (homo- and copolymers), acrylonitrile butadiene styrene rubber, nylon and polyvinyl chloride.
Подготовка
Decabromodiphenyl ether can be synthesized by reacting diphenyl ether with bromine in the presence of halogenated catalyst (iron powder, etc.).
The diphenyl ether is dissolved in the solvent, the catalyst is added, and then bromine is added to carry out the reaction. After the reaction, filter, wash and dry to obtain decabromodiphenyl ether. Commonly used solvents are dibromoethane, dichloroethane, dibromomethane, carbon tetrachloride, tetrachloroethane and the like.

Несовместимости
Incompatible with strong oxidizers (chlo-
rates, nitrates, peroxides, permanganates, perchlorates,
chlorine, bromine, fluorine, etc.); contact may cause fires
or explosions. Keep away from alkaline materials, strong
bases, strong acids, oxoacids, and epoxides. Ethers have
a tendency to form unstable and explosive peroxides.
