Directory Guidance on Carbon Tetrabromide
Product Introduction:
Carbon Tetrabromide (chemical formula: CBr₄) is a chemical substance that belongs to the category of halogenated organic compounds. Its molecule consists of one carbon atom and four bromine atoms, with a tetrahedral structure, which is similar in structure to carbon tetrachloride (CCl₄), but the chlorine in it is replaced by bromine.
Carbon Tetrabromide is usually a white solid compound with a characteristic odor and a molecular weight of about 331.6 g/mol. This compound is stable at room temperature, but may decompose at high temperatures or under certain conditions, releasing harmful gases.
Carbon Tetrabromide has a high density of about 3.42 g/cm³, which is greater than the density of water and most organic solvents. It has a melting point of 88-90°C and a boiling point of 190°C. This compound is insoluble in water, but is miscible with some organic solvents (such as benzene and ether), which gives it specific solubility characteristics in chemical reactions.
Carbon Tetrabromide can be prepared in a variety of ways, one of the common methods is to obtain it by reacting carbon tetrachloride with aluminum tribromide. In industrial production, its preparation process requires strictly controlled conditions to ensure the purity and quality of the product. Due to its high toxicity, its production and use must comply with strict safety regulations to prevent harm to the environment and human health.
Carbon Tetrabromide has stable chemical properties, but can participate in a variety of chemical reactions under specific conditions. It is mainly used as a bromination reagent in organic synthesis for the bromination of alcohol compounds and the geminal dibromination of aldehyde compounds.
In addition, it can also be used as a catalyst to promote a variety of organic transformation reactions, such as the construction of carbon-nitrogen bonds and intramolecular oxidative dehydrogenation coupling reactions. These reactions are carried out under mild and metal-free conditions, showing its importance in synthetic chemistry.
In terms of the environment, Carbon Tetrabromide is considered a hazardous substance. It degrades slowly in the natural environment and may cause pollution to water sources and soil. Therefore, special care is needed when disposing of its waste to prevent it from having a negative impact on the ecosystem.
Due to its high toxicity and environmental hazards, many countries and regions have formulated strict regulatory policies for the production and use of Carbon Tetrabromide to reduce its potential risks and impacts.

What Are The Uses of Carbon Tetrabromide
Product service:
Carbon Tetrabromide (CBr4), as an important organic synthesis intermediate, has a wide range of applications in multiple industries.
Chemical synthesis field:
Carbon Tetrabromide plays the role of bromination reagent in chemical synthesis, especially for bromination of alcohol compounds. It can convert alcohols into corresponding bromides, which is a critical process in organic synthesis.
In addition, it can also be used for geminal dibromination of aldehyde compounds to generate corresponding alkenyl dibromide compounds. These reactions are particularly important in the fields of drug synthesis and pesticide production because they help to build complex molecular structures.
Catalytic effect in organic reactions:
Carbon Tetrabromide can also be used as a catalyst in some organic reactions, especially in bromination reactions. It promotes certain chemical reactions by generating bromine free radicals or bromide ions. This catalytic effect helps to improve the efficiency and selectivity of the reaction, thereby increasing the yield and purity of the product.
Plastic and rubber industry:
In the plastic and rubber industry, Carbon Tetrabromide is used as an additive for blow molding and vulcanization, which helps to improve the processing properties of the material and the quality of the final product. Due to its non-flammable properties, it is also used as a component of certain fire-resistant chemicals to enhance the flame retardant properties of materials.
Agricultural chemicals:
Carbon Tetrabromide is used as an intermediate for pesticide raw materials to synthesize compounds with insecticidal, fungicidal or herbicidal activity. These pesticide products play an important role in modern agricultural production, protecting crops from pests and diseases.
Pharmaceutical manufacturing:
In the pharmaceutical field, Carbon Tetrabromide is used to manufacture drugs such as anesthetics. It provides the possibility of introducing bromine atoms in the design and synthesis of drug molecules, which is of great significance for improving the physicochemical properties and biological activity of drugs.
Dyes and analytical chemistry:
Carbon Tetrabromide is also used as a dye intermediate and analytical chemical reagent. In the dye industry, it helps to synthesize dye molecules with specific color properties. In analytical chemistry, Carbon Tetrabromide can be used as a reagent in certain analytical processes to help scientists perform precise chemical analysis.
In summary, Carbon Tetrabromide plays an important role in chemical synthesis, plastic and rubber industry, agricultural chemicals, pharmaceutical manufacturing, dyes and analytical chemistry due to its unique chemical properties.
Safety Precautions of Carbon Tetrabromide
Carbon Tetrabromide (CBr₄) is a toxic chemical that requires special care in its use and handling to ensure the safety of operators and the environment. Its toxicity, volatility and potential environmental hazards require strict safety regulations to be followed when used in laboratories and industries.
1. Toxicity and Health Risks
Carbon Tetrabromide is potentially toxic to humans and long-term or high-concentration exposure may cause health problems. Inhalation of its vapor, skin contact or accidental ingestion may cause adverse reactions.
Respiratory System Irritation: Inhalation of Carbon Tetrabromide vapor may cause respiratory irritation, leading to coughing, sore throat and difficulty breathing.
Skin and Eye Irritation: Skin contact with Carbon Tetrabromide may cause redness and irritation, while eye contact may cause irritation and discomfort.
Nervous System Effects: Long-term exposure to high concentrations of Carbon Tetrabromide can cause effects on the nervous system, manifested as symptoms such as headache, dizziness and nausea.
Hepatotoxicity: High concentrations or long-term exposure may affect liver function and cause liver damage.
2. Protective measures
In order to use Carbon Tetrabromide safely, the following protective measures need to be taken:
Wear personal protective equipment: Wear appropriate personal protective equipment such as protective gloves, laboratory coats and protective glasses when using it. If possible, use a mask or respirator to prevent inhalation of its harmful vapors.
Ventilated environment: Use Carbon Tetrabromide in a well-ventilated environment, preferably using a fume hood to reduce the accumulation of gas in the air. Make sure that the laboratory ventilation system can effectively remove toxic gases.
Avoid skin contact: Avoid direct contact of Carbon Tetrabromide with the skin during operation, and handle it carefully when using it to prevent liquid splashing.
Avoid ingestion: Do not eat, drink or smoke when handling chemicals to avoid accidental ingestion.
