Freon

Freon is a brand name for a group of chlorofluorocarbons (CFCs), which are types of chemical compounds that were widely used in the 20th century as refrigerants in air conditioners and refrigerators.

History[edit | edit source]

Freon was first synthesized in the late 1920s by Thomas Midgley Jr. and his team at General Motors. It was marketed by the company as a safe, non-toxic replacement for ammonia, which was commonly used as a refrigerant at the time but was highly toxic and corrosive.

Composition[edit | edit source]

Freon is a mixture of different types of chlorofluorocarbons, each with a different molecular structure. The most common types of Freon are R-12, R-22, and R-134a. R-12 is a dichlorodifluoromethane, R-22 is a chlorodifluoromethane, and R-134a is a tetrafluoroethane.

Uses[edit | edit source]

Freon was widely used as a refrigerant in air conditioners and refrigerators until the 1980s, when it was discovered that it was contributing to the depletion of the ozone layer. Since then, its use has been phased out in many countries, and it has been replaced by other types of refrigerants that are less harmful to the environment.

Health and Environmental Effects[edit | edit source]

Exposure to Freon can cause a variety of health effects, including skin and eye irritation, dizziness, and in severe cases, unconsciousness or death. It can also cause damage to the liver and kidneys.

Freon is also harmful to the environment. When it is released into the atmosphere, it can contribute to the depletion of the ozone layer, which protects the Earth from the sun's harmful ultraviolet rays.
