Cfc 11 formula. Trichlorofluoromethane also called freon-11 CFC-11 or R-11 is a chlorofluorocarbon CFC. It is a colorless faintly ethereal and sweetish-smelling liquid that boils around room temperature. CFC-11 is a Class 1 ozone-depleting substance which damages Earths protective stratospheric ozone layer.

Dichlorodifluoromethane R-12 is a colorless gas usually sold under the brand name Freon-12 and a chlorofluorocarbon halomethane CFC used as a refrigerant and aerosol spray propellantComplying with the Montreal Protocol its manufacture was banned in developed countries non-article 5 countries in 1996 and developing countries article 5 countries in 2010 out of concerns about its. Pulmonary uptake of inhaled CFC-11 by rabbits and dogs is prompt. Peak circulating concentrations after exposure at 4500 to 5000 ppm were achieved in 15 seconds with steady-state reached at 20 minutes.

Elimination is relatively rapid. Dogs exhaled within 1 hr essentially all the CFC-11 inhaled during a 6 to 20 min exposure at 5000 ppm. Inhaled CFC-11 was promptly detected in blood.

This product contains trichloromonofluoromethane CFC-11 dichlorodifluoromethane CFC-12 and dichlorotetrafluoroethane CFC-114 substances which harm the environment by destroying ozone in the upper atmosphere. The contents of Combivent ipratropium bromide and albuterol sulfate Inhalation Aerosol are under pressure.

Do not puncture the. For example the CFC number of 11 indicates the number of atoms of carbon hydrogen fluorine and chlorine eg. CCl 3 F as CFC-11.

The best way to remember the system is the rule of 90 or add 90 to the CFC number where the first digit is the number of carbon atoms C the second digit is the number of hydrogen atoms H and the third digit is number of the fluorine atoms F. Global average abundances of the major well-mixed long-lived greenhouse gases - carbon dioxide methane nitrous oxide CFC-12 and CFC-11 - from the NOAA global air sampling network since the beginning of 1979. These five gases account for about 96 of the direct radiative forcing by long-lived greenhouse gases since 1750.

The remaining 4 is contributed by 15 other halogenated gases. This is measured in tonnes of chlorofluorocarbon-11-equivalents CFC 11 equivalents. CFC 11 equivalents is a standardized measure to normalise the sum of a range of ozone-depleting substances to a value equivalent to their potential to deplete ozone.

As we describe in our Data Quality Definitions section depleting substances are weighted by their potential to destroy ozone. CCl 2 F 2. Table 16b Some Halogenated Hydrocarbons Derived from CH 3 CH 3.
