Chloroflourocarbons: Uses & Dangers

Chloroflourocarbons were discovered in the 1920’s by Thomas Midgley, an organic chemist at General Motors Corporation. He was looking for inert, non-toxic, non-flammable compounds with low boiling points that could be used as refrigerants. He found what he was looking for in the form of two compounds: dichlorodifluoromethane (CFC-12) and trichloromonoflouromethane (CFC-11). In both compounds,…
