Carbon tetrachloride is a volatile, colourless, clear, heavy liquid with a characteristic sweet, non-irritant odour. The odour threshold in water is 0.52 mg/litre, and in air it is >64.1 mg/m³ (10 ppm). Carbon tetrachloride is miscible with most aliphatic solvents and it is a solvent itself. The solubility in water is low. It is non-flammable and fairly stable in the presence of air and light. Decomposition of carbon terachloride forms phosgene, carbon dioxide and hydrochloric acid. It reacts explosively with aluminium powder and some other reactive metals, and, in the presence of peroxides or light, with unsaturated compounds. The most important physical and chemical properties of carbon tetrachloride are presented in the Summary of Chemical Safety Information

Carbon tetrachloride is an organic chemical that is commonly used as a solvent. It is also called tetra chloromethane and is composed of molecules that have one carbon atom and four chlorine atoms bonded together in the shape of a tetrahedron. It is made by combining elemental chlorine with simple carbon compounds like methane or carbon disulfide. It is a liquid at room temperature, with a freezing point of -9.4°F (-23°C) and a boiling point of 170.6°F (77°C). Carbon tetrachloride dissolves other organic materials such as oils, fats, and grease very well. This property makes carbon tetrachloride very useful for cleaning manufactured parts. Carbon tetrachloride was once used heavily in the dry-cleaning industry. Use in that industry has declined because it is toxic when inhaled or absorbed through the skin, and it is no longer used in products for the home. Since carbon tetrachloride is a good solvent, it is used to dissolve things like oils, fragrances, and colors from flowers and seeds. Carbon tetrachloride is not flammable, so it can be used in fire extinguishers or as an additive to make other chemicals nonflammable. It is also very useful as a raw material in synthesizing larger, more complicated organic compounds. Because of the health hazards of long-term exposure to carbon tetrachloride, it should only be used where there is adequate ventilation present.

Local: Carbon Tetrachloride, also called tetrachloromethane, is a colourless, dense, highly poisonous, highly volatile and nonflammable liquid with a characteristic aromatic odour, belonging to the family of organic halogen compounds. Carbon tetrachloride freezes at -23 C and boils at 77 C. It is sparingly soluble in water. When heated to decomposition, it forms highly toxic fumes of phosgene and hydrogen chloride. It is prepared by the reaction of chlorine with carbon disulfide or with methane in the presence of a catalyst. It is used principally in the manufacture of freon refrigerants e.g., dichlorodifluoromethane (Freon-12) and propellants for aerosol cans. Carbon tetrachloride is known to deplete the ozone layer. It's half-life is more than 30 years. It was used as a dry cleaning solvent and for degreasing metals as it is not flammable and is a good solvent for fats, oils, and greases. Due to the property of much denser than air, it is used in fire extinguishers in mixtures with potent fumigants to reduce the fire hazard, to render benzene nonflammable and separate xylene isomers as components to reduce flammability. In veterinary medicine, it was used as an anthelmintic and to treat liver fluke infections in sheep. In polymer industry, it was used as a reaction medium, catalyst and chain transfer agent, as a solvent for resins. In organic synthesis, it was useful as a feedstock for chlorination of organic compounds used in soap perfumery and insecticidal industries. In automobiles, it was used as an azeotropic drying agent for wet spark plugs. It was also used in petroleum refining, pharmaceutical manufacturing, and general solvent use. It was used as a general purpose nonflammable solvents. But the production and use of 1,1,1-trichloroethane and carbon tetrachloride have been phased out throughout the world because of suspected harm to the earth's ozone layer.
