Carbon tetrachloride formula

CCl4 is a colourless liquid with a sweet odor. It is a chemical compound that has been widely used in cleaning agents and fire extinguishers. However, its use has been phased out because of the many health and environmental risks associated with it.

Structure of CCl4 (Chemical)

The IUPAC name of CCl4 is 1,1,1-tetrachloromethane, as it is named because of the molecule’s tetrahedral molecular geometry, where the central carbon atom is bonded to four chlorine atoms by a single covalent bond. The molecule is highly stable and resistant to breaking down.

It is miscible with polar solvents such as water and ethanol to a lesser extent, while it is soluble in nonpolar solvents. The molecule is able to cross the blood-brain barrier and has been shown to be toxic to human beings, especially when exposed for long periods of time.

Potential sources of CCl4

In its raw form, carbon tetrachloride is produced by thermal chlorination or hydrochlorination of methane using a variety of catalysts. Other methods include the production of tetrachloroethylene by phosgene catalysis or methane oxychlorination and the generation of liquid chlorine by high-pressure chlorination of methanol.

Applications of CCl4

Before the 1980s, carbon tetrachloride was used extensively in the production of chlorofluorocarbons for refrigeration purposes. Several countries have banned its use in this capacity due to environmental and health concerns. It has also been found to be harmful to the Earth’s ozone layer. In addition, it is an effective hepatotoxin and has been linked to cancer.
