Los clorofluorocarburos (CFC), clorofluorocarbonos o gases clorofluorocarbonados son derivados de los hidrocarburos saturados obtenidos mediante la sustitución de átomos de hidrógeno por átomos de flúor y/o cloro principalmente. Los CFC, son una familia de gases que se emplean en diversas aplicaciones… WebThe 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). This sometimes caused fatalities from leakage of these products. This is the reason many people placed their refrigerator in the back yard.
