Chlorofluorocarbon One of the key reaction of the CFCs is: CCl3F → CCl2F. + Cl. In this reaction one Cl atom dissociate from CCl3F in presence of light. CFC or chlorofluorocarbon goes under dissociate reaction in ultraviolet radiation and produce dichlorodifluoromethane, a chlorine radical which is highly reactive: The chlorine free radicals take the ozone from the atmosphere and produce highly reactive ClO and oxygen. In the second layer of earth’s atmosphere, also known as stratosphere the ozone continuously
Jr., a world-renowned chemist at the time, and requested that he pursue research into possible alternative coolants. Midgley’s research led him to consider carbon tetrafluoride and dichlorodifluoromethane.2 Both possessed stability, a non-reactive nature, and fire extinguishing characteristics, but dichlorodifluoromethane was nominated as the preferable option because its boiling point was better suited to the mechanics of refrigerators. This new co... ... middle of paper ... ... to Susan Strahan
Ozone Depletion Atmospheric ozone layer depletion is a serious problem currently facing the world. The ozone layer protects humans, animals, and plants from harmful ultraviolet rays. Money and time are being spent on ozone repair, but the problem still exists. The ozone layer is a region of the stratosphere containing ozone, or O3 gas. The ozone layer is essential to both plant and animal life on earth because it protects the surface from dangerous ultraviolet light. However, industrial
The basis behind scientific research is to have a better understanding of the world we live in and how humans may further improve their current lifestyle. But should the scientists behind the research be held accountable for the impact their work has on future lifestyle? Should the scientists behind the discovery of greenhouse gasses be responsible for global warming? Should the scientists behind nuclear fusion be responsible for the outcome of the Hiroshima and Nagasaki bombings in World War II
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, different amounts of chlorine and fluorine are combined with methane, which is a combination of carbon and hydrogen. These two CFCs were eventually manufactured by E.I. du
Facts Since January 1st 1999, it had been illegal to import products into Canada containing dichlorodifluoromethane, a chlorofluorocarbon (CFC) also described as CFC 12 or R12. In the year 1999, over 4000 of Canadian Tire’s imported fridges contained CFC. However, any fridges imported before January 1st 1999 containing CFC could still be sold until the existing supply was depleted. By April of 2000, inspectors across the country, together with the investigation Branch of Environment Canada became
One hundred years from now the once habitual and prosperous Earth has become chaotic and unlivable. There are endless droughts and intense storms that annihilate everything in their path. Entire species have gone extinct while the ones left alive struggle to fight for survival and dominance until nothing is left. This is Earth; the plant that millions of life forms have called home has become a desolate world. This “future” is a result of Homo sapiens, simply referred to as humans, interfering with
Los Clorofluorocarbonados (CFCs) Los Clorofluorocarbonados (CFC) y sus derivados tienen como fuentes principales algunos productos industriales, y los óxidos de nitrógeno, que se producen por multitud de causas, principalmente por la quema de combustibles fósiles y la utilización de fertilizantes químicos. La producción de cloro-fluoro-carbonos [CFCs] contribuye con aproximadamente el 14% del efecto invernadero. Los CFCs son sustancias químicas sintéticas, formadas por cloro, flúor y carbono.
