Because CFCs have important uses in modern society as the working fluids in refrigerators and air-conditioners, and as the blowing agents for plastic foams, tbe response to phasing them out has been an intensive search for alternatives which retain their desirable properties in terms of volatility and low toxicity, but which are environmentally friendly. The environmental problems to be overcome in finding a CFC replacement are the following ...
