Excerpt
Introduction: Dichlorodifluorornethane (CCl,F2) is an industrial gas, which was widely used as a refrigerant, a foam blowing agent, and an aerosol propellant. It is also a plasma processing and has been used as an additive in gas dielectric mixtures. Dichlorodifluoromethane is of atmospheric and environmental interest because it is an ozone depleting gas due...
