An example of a refrigerant CFC is dichlorodifluoromethane, CF2Cl2 (also known as CFC-12), which boils at -30°C. Another once-common CFC is trichlorofluoromethane, CFCl3 (CFC-11), which boils at 24°C and was once the propellant in around half of all the aerosol cans used in the world. Why were CFCs banned? Chlorofluorocarbon (CFC), any of several organic compounds composed of carbon, fluorine, and chlorine. When CFCs also contain hydrogen in place of one or more chlorines, they are called hydrochlorofluorocarbons, or HCFCs.

CF4 is a strong greenhouse gas that contributes to climate change and has an atmospheric lifetime of 50,000 years. Even worse, CFC’s are super greenhouse gases which contributes to global warming and climate change at a much greater rate than even carbon dioxide.

2013-5-30 For example, CFC-R12 has a lifetime of approximately 100 years, while other CFCs can last from 45 to 1700 years. One standard for measuring and comparing greenhouse gases is the Global Warming Potential (GWP). It quantifies the amount of heat a gas traps, and how long the effect lasts depending on the lifetime of the gas. The History of CFC. Early refrigeration products from the late 19th century to the early 20th century used toxic gases like ammonia (NH3), methyl chloride (CH3CI), and sulfur dioxide (SO2).
