Carbon tetrachloride, a colorless liquid with a sweet odor, was once commonly used in everyday products like cleaning solvents and fire extinguishers. However, due to its harmful effects on human health and the environment, its use has been restricted. While it may not be widely used in consumer products today, carbon tetrachloride is still relevant in industries such as chemical manufacturing and as a solvent for certain chemical reactions. Its importance lies in its role as a key industrial chemical, albeit with stricter regulations to mitigate its negative impact.

💡 Commercial Applications
Carbon tetrachloride, historically used as a versatile solvent in various commercial and industrial applications due to its excellent solvent properties. It has been used for dry cleaning fabrics, as a degreasing agent in the automotive and metalworking industries, and as a refrigerant in air conditioning systems.
In regard to drug and medication applications, carbon tetrachloride has been utilized in the past as a pharmaceutical agent in the treatment of parasitic infections and as an anthelmintic to expel worms from the digestive system. However, due to its toxic and carcinogenic nature, its use in medical applications has been largely phased out in favor of safer alternatives.
⚗️ Chemical & Physical Properties
Carbon tetrachloride, a colorless liquid, possesses a sweet, chloroform-like odor. It is non-flammable and volatile, making it easily vaporizable at room temperature.
With a molar mass of 153.8 g/mol and a density of 1.586 g/cm^3, carbon tetrachloride is heavier than many common household items. For example, water has a molar mass of 18 g/mol and a density of 1 g/cm^3, making it significantly lighter than carbon tetrachloride.
Carbon tetrachloride has a melting point of -22.9°C and a boiling point of 76.7°C. Compared to common household items such as water (melting point of 0°C, boiling point of 100°C), carbon tetrachloride has lower melting and boiling points.
Although carbon tetrachloride is insoluble in water, it is miscible with many organic solvents. It exhibits low viscosity, making it less thick and sticky compared to household items like honey or syrup.
🏭 Production & Procurement
Carbon Tetrachloride, a colorless liquid with a sweet odor, is primarily produced by the reaction of chlorine gas with carbon disulfide. This chemical process involves the chlorination of methane or chloroform, resulting in the production of Carbon Tetrachloride as a byproduct. This compound is commonly used as a solvent, as well as in the production of various industrial chemicals.
The procurement of Carbon Tetrachloride involves obtaining the compound from chemical manufacturing companies or suppliers. It is commonly stored and transported in sealed containers, such as metal drums or tanks, to prevent leakage or evaporation. Due to its harmful effects on human health and the environment, precautions should be taken during its handling and transportation.
Transportation of Carbon Tetrachloride is typically carried out using specialized vehicles equipped with safety features to prevent spills or leaks. The compound is classified as a hazardous material and must adhere to strict regulations set forth by government agencies. Proper labeling and documentation are required for the transportation of Carbon Tetrachloride to ensure compliance with safety standards.
⚠️ Safety Considerations
Safety Considerations for Carbon Tetrachloride:
Carbon tetrachloride is a highly toxic and potentially lethal compound that poses serious health risks to humans. Exposure to carbon tetrachloride can occur through inhalation, skin contact, or ingestion. It is important to handle this chemical with extreme caution to avoid any accidental exposure.
When working with carbon tetrachloride, it is crucial to use appropriate personal protective equipment such as gloves, goggles, and a lab coat to prevent direct skin contact and inhalation. Additionally, it is recommended to work with this compound in a well-ventilated area to reduce the risk of harmful exposure.
It is essential to store carbon tetrachloride in a secure, cool, and well-ventilated area away from sources of ignition to prevent accidental fires. Proper labeling and handling procedures should be followed at all times to minimize the risk of exposure to this hazardous chemical.
Pharmacology of Carbon Tetrachloride:
Carbon tetrachloride is a colorless liquid with a sweet odor that was once used as a solvent in industrial processes but is now primarily used in chemical synthesis. When ingested or inhaled, carbon tetrachloride is metabolized by the liver into toxic compounds that can cause severe damage to liver cells.
The toxicity of carbon tetrachloride is due to its ability to induce oxidative stress and lipid peroxidation, leading to liver damage and potentially liver failure. Due to its harmful effects on the liver, carbon tetrachloride is no longer used in consumer products and is strictly regulated in industrial settings.
Hazard Statements for Carbon Tetrachloride:
Carbon tetrachloride is classified as a toxic and potentially fatal chemical that can cause serious harm to human health. Hazard statements for carbon tetrachloride include “Fatal if swallowed,” “Causes skin irritation,” and “May cause damage to organs through prolonged or repeated exposure.”
Exposure to carbon tetrachloride should be avoided at all costs, as it can lead to severe health complications and even death. Proper safety precautions must be taken when handling this compound to prevent any accidental exposure that could result in serious harm.
Precautionary Statements for Carbon Tetrachloride:
When working with carbon tetrachloride, it is important to wear appropriate personal protective equipment, including gloves, goggles, and a lab coat, to minimize the risk of exposure. It is also recommended to work with this compound in a well-ventilated area to reduce the concentration of vapors in the air.
Proper storage and handling procedures should be followed to prevent accidental spills or leaks of carbon tetrachloride. In case of exposure, immediate medical attention should be sought, and contaminated clothing should be removed and discarded properly to prevent further exposure.
🔬 Potential Research Directions
One potential research direction for Carbon Tetrachloride is its environmental impact. Studies could investigate its persistence in the atmosphere and soil, as well as its potential for leaching into groundwater sources.
Another avenue of research could focus on the health effects of Carbon Tetrachloride exposure. This could include studies on its impact on human health, as well as its potential carcinogenic properties and long-term effects on biological systems.
Additionally, research could explore ways to mitigate the release of Carbon Tetrachloride into the environment. This could involve developing alternative production methods or technologies for capturing and sequestering the compound to prevent its spread and accumulation in the environment.
