Description
Decabromodiphenyl oxide, also known as Decabromodiphenyl ether (DecaBDE), is a polybromodiphenyl ether that is diphenyl ether in which all of the hydrogens have been replaced by bromines. It is a white to off-white powder with a chemical odor and is recognized for its role as a neurotoxin. Decabromodiphenyl oxide is characterized by its good thermal stability and is considered a non-toxic and non-polluting flame retardant.
Uses
Used in Plastics/Polymers/Composites Industry:
Decabromodiphenyl oxide is used as an additive flame retardant for its thermal stability and low cost in high impact polystyrene, glass reinforced thermoplastic polyester, and moulding resins. It is particularly useful in the production of housings for computers and TVs, wires and cables, and pipes.
Used in Textile Industry:
In the textile industry, Decabromodiphenyl oxide is employed as an additive flame retardant to enhance the fire resistance of various fabrics, including carpets.
Used in Adhesives and Sealants Industry:
Decabromodiphenyl oxide is utilized as an additive flame retardant in the production of adhesives and sealants, providing improved fire safety properties.
Used in Coatings and Inks Industry:
This additive flame retardant is also used in the coatings and inks industry to enhance the fire resistance of these materials.
Environmental and Health Concerns:
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.
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

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.
Check Digit Verification of cas no
The CAS Registry Mumber 1163-19-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,6 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1163-19:
(6*1)+(5*1)+(4*6)+(3*3)+(2*1)+(1*9)=55
55 % 10 = 5
So 1163-19-5 is a valid CAS Registry Number.

PREPARATION OF HIGH ASSAY DECABROMODIPHENYL OXIDE

Page/Page column 6-7, (2008/06/13)
A process is described for producing a reaction-derived decabromodiphenyl oxide product of high purity. In a continuous bromination process, partially brominated diphenyl oxide and coproduct hydrogen bromide are formed by bringing together elemental bromine and diphenyl oxide continuously in a first reaction zone. The partially brominated diphenyl oxide formed has an average of about 2-6 bromine atoms per molecule. The vapor phase and the partially brominated diphenyl oxide are removed continuously from the first reaction zone as separate entities. Then, or after storage, partially brominated diphenyl oxide is fed to a second reaction zone. This zone contains a refluxing reaction mixture comprising (i) an excess of bromine and (ii) a catalytic quantity of Lewis acid bromination catalyst. As the reaction in this zone is taking place, hydrogen bromide coproduct is removed therefrom in a sufficient amount to form a reaction-derived decabromodiphenyl oxide product of high purity.

This invention provides a process of preparing reaction-derived decabromodiphenyl oxide product of high purity. The process comprises feeding a solution comprising a solvent and diphenyl oxide and/or partially brominated diphenyl oxide into a reaction zone containing a refluxing reaction mixture comprising an excess of bromine and a catalytic amount of Lewis acid bromination catalyst. Substantially concurrently with the feeding, a sufficient amount of hydrogen bromide coproduct is removed from the reaction zone so as to form a reaction-derived decabromodiphenyl oxide product of high purity.

Process technology for producing very pure reaction-derived decabromodiphenyl oxide is described. Diphenyl oxide or partially brominated diphenyl oxide or a mixture of either or both of these is fed substantially continuously over a period of about 2 to about 12 hours into a reactor containing an excess of refluxing bromine containing Lewis acid bromination catalyst, and substantially concurrently reducing the content of hydrogen bromide present in the reactor whereby a decabromodiphenyl oxide product having a purity of over 99%, preferably 99.5% or more, is formed in the reactor.
