Tetrabromodiphenyl Ether (commonly Referred To As TetraBDE) Is One Of Several Polybrominated Diphenyl Ethers (PBDEs), Which Are A Group Of Chemicals Used As Flame Retardants. These Compounds Are Characterized By Their Bromine Content, Which Helps Them To Inhibit Combustion.
Chemical Specifications:
- Chemical Name: Tetrabromodiphenyl Ether
- Chemical Formula: C12H6Br4O
- Molecular Weight: Approximately 485.8 G/mol
- Appearance: Typically A White To Off-white Solid
- Boiling Point: Not Well-defined Due To Decomposition Before Boiling
- Melting Point: Around 95-100°C
- Density: Varies, But Generally Around 2.1 G/cm³
- Solubility:
- Water: Very Low Solubility
- Organic Solvents: Generally Soluble In Organic Solvents Like Acetone, Chloroform, And Toluene
Chemical Properties:
- Stability: TetraBDE Is Relatively Stable Under Normal Conditions, But It Can Degrade Under UV Light Or High Temperatures.
- Reactivity: It Does Not React Readily With Most Substances, But Can React With Strong Oxidizing Agents.
Safety And Environmental Considerations:
- Toxicity: PBDEs, Including TetraBDE, Are Known To Be Persistent In The Environment And Can Accumulate In Living Organisms. They Are Associated With Various Health Risks, Including Potential Impacts On Thyroid Function And Developmental Issues.
- Regulation: Due To Concerns About Environmental And Health Effects, Many Countries Have Placed Restrictions Or Bans On The Use Of PBDEs, Including TetraBDE.
Applications:
TetraBDE Is Used Primarily As A Flame Retardant In Various Materials Such As Textiles, Electronics, And Building Materials. However, Due To Environmental And Health Concerns, Its Use Has Been Phased Out In Many Regions, And Safer Alternatives Are Being Sought.
