Carbon tetrachloride has been widely used in various industrial applications, though its use has significantly declined due to its toxicity and environmental impact. Historically, it was a common solvent in dry cleaning and degreasing processes, effectively removing oils and fats from machinery and fabrics. It was also employed as a fire extinguishing agent, particularly in extinguishers designed for electrical fires, due to its non-flammable nature. In the chemical industry, it served as a feedstock for the production of refrigerants and propellants, such as chlorofluorocarbons (CFCs). Additionally, it was utilized in the synthesis of other chemicals, including pharmaceuticals and agricultural products. However, its use has been largely phased out in many countries due to its harmful effects on human health and the ozone layer.
