- Common name: Freon English: CFC or chlorofluorocarbon
- CFCs are colorless gases or volatile liquids at room temperature, with a slight fragrance, low toxicity, and stable chemical properties. The most important of these is dichlorodifluoromethane CCl2F2 (F-12). Dichlorodifluoromethane is a colorless gas at normal temperature and pressure; its melting point is 158 ° C, boiling point is -29.8 ° C, density is 1.486 g / cm (-30 ° C), and it is slightly soluble in water.
- Consumers who care for the ozone layer purchase products bearing the "CFC-free" mark; the owner who cares for the ozone layer properly disposes of used refrigerators and appliances, and removes CFCs and HCFC refrigerants before discarding appliances .
