| | Decabromodiphenyl oxide Usage And Synthesis |
| Chemical Properties | 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. | | Uses | Decabromodiphenyl ether is a brominated flame retardant that is used in conjunction with antimony trioxide in high impact polystyrene. DecaBDE is used as an additive flame retardant, and has a variety of applications including in plastics/polymers/composites, textiles, adhesives, sealants, coatings and inks. DecaBDE containing plastics are used in housings of computers and TVs, wires and cables, pipes and carpets. Adverse effects are reported for soil organisms, birds, fish, frog, rat, mice and humans. One of the new POPs under the Stockholm Convention | | Definition | ChEBI: Decabromodiphenyl ether is a polybromodiphenyl ether that is diphenyl ether in which all of the hydrogens have been replaced by bromines.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. | | Application | 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. | | Preparation | 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. | | General Description | White to off-white powder with a chemical odor. | | Air & Water Reactions | Insoluble in water. | | Reactivity Profile | Decabromodiphenyl oxide is incompatible with strong oxidizers . | | Fire Hazard | Flash point data for Decabromodiphenyl oxide are not available; however, Decabromodiphenyl oxide is probably combustible. | | Safety Profile | Questionable carcinogen with experimental neoplastigenic data. Experimental reproductive effects. Used as a flame retardant for thermoplastics. When heated to decomposition it emits toxic fumes of Br-. See also ETHERS and BROMIDES | | Potential Exposure | It is used as a fire retardant for
thermoplastics and man-made fibers. | | Shipping | UN3077 Environmentally hazardous substances,

Polyhalogenated biphenyls, solid or Polyhalogenated ter-
phenyls, solid, Hazard class: 9; Labels: 9-Miscellaneous
hazardous material. | | Incompatibilities | 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. |
