Ccl4

Carbon tetrachloride (CCl4) is a colorless, heavy, non-flammable liquid with a sweet odor. Its chemical formula is CCl4, which means it has one carbon atom and four chlorine atoms. It is also known as tetrachloromethane.

CCl4 was widely used as a solvent for many industrial and laboratory applications in the past, including dry cleaning, degreasing metals, and as a refrigerant. However, it has since been largely phased out due to its harmful effects on human health and the environment.

Exposure to CCl4 can lead to serious health problems, including liver damage, neurological disorders, and cancer. It is also a potent greenhouse gas and depletes the Earth's ozone layer.

The use of CCl4 has been prohibited or significantly restricted by many countries, including the United States, under the Montreal Protocol on Substances that Deplete the Ozone Layer. Today, safer alternatives such as water-based solvents are used in place of CCl4 in most applications.
