Tetrabromomethane

Tetrabromomethane is a dense, colorless to pale yellow crystalline organic compound with the chemical formula CBr4. This halogenated methane derivative consists of a central carbon atom bonded to four bromine atoms, making it the fully brominated analog of methane. With a molecular weight of 331.63 g/mol, it is significantly heavier than water and exhibits high density. The compound is also known as carbon tetrabromide and serves various industrial applications requiring heavy, non-flammable solvents.

Tetrabromomethane is a crystalline solid at room temperature with a melting point of approximately 90-92°C and a boiling point of 189-190°C. It appears as colorless to pale yellow crystals with a characteristic sweet odor. The compound is practically insoluble in water but readily dissolves in organic solvents like alcohol, ether, and chloroform. It has a high density of about 3.42 g/cm³, making it one of the densest common organic compounds. The substance is chemically stable under normal conditions.

Tetrabromomethane is primarily used as a dense separation medium in mineral processing and geological applications due to its high specific gravity. It serves as a solvent in organic synthesis and as an intermediate in the production of other brominated compounds. The substance is utilized in laboratory settings for density gradient separations and as a source of bromine in various chemical reactions. Additionally, it finds application in specialized industrial processes requiring non-flammable, heavy solvents with good chemical stability.

Tetrabromomethane should be handled with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing to prevent skin and eye contact. Work in well-ventilated areas or under fume extraction systems to avoid inhalation of vapors. Avoid contact with heat sources, strong oxidizing agents, and incompatible materials. Use non-sparking tools and equipment when handling. Ensure emergency eyewash stations and safety showers are accessible. Train personnel on proper handling procedures and emergency response protocols before use.

Tetrabromomethane should be stored in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Keep containers tightly closed in original packaging, preferably in secondary containment to prevent spillage. Store away from incompatible materials such as strong bases, alkali metals, and reducing agents. Maintain storage temperature below 25°C to prevent degradation. Ensure storage areas are equipped with appropriate spill containment measures and fire suppression systems. Regular inspection of containers for damage or leakage is recommended.

In case of skin contact with tetrabromomethane, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for at least 15 minutes while holding eyelids open. If inhaled, move the person to fresh air and monitor breathing. In case of ingestion, do not induce vomiting and seek immediate medical attention. Remove contaminated clothing and wash before reuse. Seek medical advice if irritation persists or symptoms develop.

Tetrabromomethane must be disposed of as hazardous waste through licensed waste management companies in accordance with local, national, and European regulations. Do not discharge into drains, sewers, or the environment. Small quantities can be neutralized through controlled incineration at high temperatures in specialized facilities. Collect waste in compatible, labeled containers and maintain proper documentation for waste tracking. Consider recycling or recovery options where available. Consult local environmental authorities for specific disposal requirements and approved disposal facilities in your region.

Tetrabromomethane is classified under ADR Class 6.1 (Toxic substances) Packing Group III for road transport in Europe. It must be packaged in UN-approved containers with appropriate labeling and documentation including transport documents and emergency response information. Vehicles must carry appropriate safety equipment and drivers require ADR training certification. Ensure packages are properly secured, marked, and labeled according to dangerous goods regulations. Transport should avoid extreme temperatures and routes near populated areas where possible. Comply with loading limitations and segregation requirements.

Tetrabromomethane is subject to various European chemical regulations including REACH (Registration, Evaluation, Authorization and restriction of Chemicals) and CLP (Classification, Labelling and Packaging) regulations. It requires proper registration for commercial use above certain tonnage thresholds. The substance must be handled according to occupational safety regulations and transported under ADR dangerous goods legislation. While not currently listed as an SVHC (Substance of Very High Concern), users must comply with safety data sheet requirements and risk assessment obligations under REACH.
