History

They were initially developed in the early 20th century as an alternative to the toxic gases that were previously used as refrigerants, such as Thomas Midgley, Jr. with co-inventor Charles Kettering.[1] Each Freon is designated by a number; for instance, Freon-11 is trichlorofluoromethane, while Freon-12 is ozone layer.
