    Chlorofluorocarbons (CFCs) were first developed in the 1930s as safe, reliable, and non-toxic refrigerants for domestic use. Trichlorofluoromethane, known as CFC-11 or Freon-11, and dichlorodifluoromethane, known as CFC-12 or Freon-12, were the two most widely used CFCs in applications ranging from refrigerators and air conditioners to propellants in spray cans and blowing agents in foam ...

Apr 11, 2014 · CHLOROFLUOROCARBONSCHLOROFLUOROCARBONS (CFC’S)(CFC’S) chlorofluorocarbons (CFC’s) are inert, non toxic, non-inflammable used for oral and inhalation aerosols. Among the Chlorofluorocarbons trichlorofluoromethane (Propellant 11), dichlorodifluoromethane (Propellant 12) and dichlorotetrafluoroethane (Propellant 114) were initially widely used in pharmaceutical aerosols. Liquefied gases provide a nearly constant pressure during packaging operation and have large expansion ratio.

Dec 24, 2014 · Alkyl halides are seldom found in nature but can be prepared from their parent hydrocarbons. A class of simple alkyl halides called chlorofluorocarbons (CFCs) was once very widely used in aerosol sprays and as refrigerants. One such example is CCl 3 F, called trichlorofluoromethane. Unfortunately, CFCs are harmful to the ozone layer of our upper atmosphere.

1.1.2 Toxicity Hierarchy There are several sources of published toxicity parameters available on the internet and elsewhere. None of these sources is exhaustive and they do not always agree on the risk or hazard posed by a particular compound. As such, several sources were examined when developing the toxicity parameters for the analysis. volatiles like trichlorofluoromethane (CFC-11) and other CFCs (chlorinated fluorocarbons) were commonly used as blowing agents before their phase-out in North America and the European Union in the mid to late 1990s due to concerns about greenhouse gases. While it is still possible to find these blowing agents used in developing
