Chlorofluorocarbons (CFC) are gases utilized for different purposes including solvents, refrigerants and spray splashes. They are natural synthetic substances and contain carbon, (in some cases hydrogen,) chlorine, and fluorine. They were quite utilized in the center twentieth century, supplanting synthetic compounds that were poisonous or combustible or had characteristics that were by and large destructive to human wellbeing. Chlorofluorocarbons straightforwardly affect the climate overall. At the point when CFCs likewise contain hydrogen instead of at least one chlorines, they are called hydro chlorofluorocarbons, or HCFCs. CFCs are likewise called Freons. CFCs were initially evolved as refrigerants during the 1930s. A portion of these mixtures, particularly trichlorofluoromethane (CFC-11) and dichlorodifluoromethane (CFC-12), found use as spray splash forces, solvents, and froth blowing specialists [1]. They are appropriate for these and different applications since they are nontoxic and non-flammable and can be promptly changed over from a fluid to a gas as well as the other way around. Their business and modern worth in any case, CFCs were in the end found to represent a genuine natural danger. CFCs, once delivered into the air, aggregate in the stratosphere, where they add to the consumption of the ozone layer. Stratospheric ozone safeguards life on Earth from the destructive impacts of the Sun's bright radiation. Bright radiation in the stratosphere makes the CFC particles separate, creating chlorine molecules and revolutionaries (i.e., chlorodifluoromethyl extremist; free revolutionaries are species that contain at least one unpaired electrons) [2].

The interest for the CFCs was accomodated by reusing, and reuse of existing supplies of CFCs and by the utilization of substitutes. A few applications, for instance degreasing of metals and cleaning solvents for circuit loads up, that once utilized CFCs currently use sans halocarbon liquids, water (once in a while as steam), and weakened citrus extracts [3]. Chlorofluorocarbons are utilized in an assortment of uses as a result of their low harmfulness, reactivity and combustibility. Each stage of fluorine, chlorine and hydrogen-in view of methane and ethane has been inspected and most have been marketed. Moreover, numerous models are referred to for larger quantities of carbon as well as related compounds containing bromine. Utilizes incorporate refrigerants, blowing specialists, forces in therapeutic applications and degreasing solvents [4].

Notwithstanding, the air effects of CFCs are not restricted to their job as ozone-exhausting synthetic compounds. Infrared retention groups keep heat at that frequency from getting away from the world's air. CFCs have their most grounded assimilation groups from C-F and C-Cl bonds in the unearthly area of 7.8-15.3 µm-alluded to as "environmental window" because of the general straightforwardness of the air inside this district. The strength of CFC retention groups and the one of a kind vulnerability of the climate at frequencies where CFCs (for sure all covalent fluorine compounds) retain makes a "super" ozone depleting substance (GHG) impact from CFCs and other inert fluorinecontaining gases like perfluorocarbons, HFCs, HCFCs, bromofluorocarbons. As indicated by mainstream researchers, the opening in the ozone layer has started to recuperate because of CFC boycotts. India is one of a handful of the nations that are pioneers in the utilization of non-Ozone Depleting innovations and have a low Global Warming Potential (GWP) [5,6].
