One Chloroflurocarbon Which Was Widely Used as a Solvent Is

Aerosol propellants solvents in the cleaning of electronic components and metals refrigerants and the blowing agents in foam plastic manufacturing. Carbon tetrachloride also known as tetrachloromethane is an organic compound with the chemical formula CCl4.

Chlorofluorocarbon An Overview Sciencedirect Topics

CFCs have been used widely in fire extinguishers and as solvents refrigerants aerosol propellants and in the manufacture of foam plastics.

. Chlorofluorocarbon CFC One of a range of chemically inert compounds in which a chlorinated hydrocarbon is treated with hydrogen fluoride eg. Dichlorodifluoromethane is by far the most common example R-12 or Freon-12 of CFC gas. Some of these compounds especially trichlorofluoromethane CFC-11 and dichlorodifluoromethane CFC-12 found use as aerosol-spray propellants solvents and foam-blowing agents.

D processes that use water as a solvent require more energy. They are man-made gas. This compound is often classified as a polyhalogenated organic compound since it consists of a carbon atom which is attached to more than one halide functional group.

Du Pont de Nemours Company in Wilmington Del. CFCs were originally developed as refrigerants during the 1930s. Commonly known by the name freon the manufacture of CFCs.

HCFC-132b terpene solvent water D flammable D limited utility. One drawback to the use of water as a solvent in the production of organic compounds is that A the reaction times are longer. One tonne of CFC-11 is equivalent to around 5000 tonnes of CO2 leading not only to a decline in the ozone layer but also an increase in the earths overall temperature.

In the aerosol area CFCs such as tricholorfluoromethane CCl 3 F CFC-11 and dichlorodifluoromethane CCl 2 F 2 were normally packed with materials like paint. Chlorofluorocarbons Used widely as cleaning solvent propellant blowing agent refrigerant Ideal low boiling point Low toxicity Non-flammable non-explosive CFCs are mostly banned for these uses because of they deplete the stratospheric ozone layer. What is CFC Gas.

C many organic compounds do not dissolve readily in water. Many CFCs have been used as. Under standard conditions for temperature and pressure CCl4 exists as a.

CFC-12 is CCl 2 F 2 CFC-21 is CHCl 2 F. They were used to manufacture aerosol sprays and plastic foams as cleaning solvents packing materials and refrigerants. CCl 2 FCCl F 2.

It contains carbon chlorine and fluorine produced as a volatile derivative of methane ethane and propane. Chlorofluorocarbons CFCs and hydrochlorofluorocarbons HCFCs were developed in the US in the early 20th century and became widely used as refrigerants and for making plastic foams producing refrigerators and freezers until the early 1990s when it was found that these chlorinated gases damaged the ozone layer. Chlorofluorocarbon is an organic compound that does not occur naturally.

CFCs were widely used in four areas. B the organic compounds produced must be separated from water but not from organic solvents. Under the Montreal Protocol the use of chlorofluorocarbons is to be phased out Fluorocarbons are often used to replace them.

CFCs are also called Freons a trademark of the EI. Chlorofluorocarbons chemical formula is CCl 2 F 2. CFCs were first formulated in the 1930s as a refrigerant.

Fluorocarbons are often used to replace them. One chlorofluorocarbon which was widely used as a solvent is CC12FCClF2 and large stocks of it remain. Any of several simple gaseous compounds that contain carbon chlorine fluorine and sometimes hydrogen that are used as refrigerants cleaning solvents and aerosol propellants and in the manufacture of plastic foams and that are believed to be a major cause of stratospheric ozone depletion abbreviation CFC.

One process to use up these stocks is to convert it into the fluorocarbon CH2FCF3 by the following route. 21 Under the Montreal Protocol the use of chlorofluorocarbons is to be phased out. CFCs are non-toxic non-flammable and very.

CFC-11 trichlorofluoromethane is one of a number of chlorofluorocarbons CFC chemicals that were initially developed as refrigerants during the 1930s. 1975 and with the knowledge that the use of CFCs had been growing since the late 1950s the stage seemed set for an increasingly rapid thinning of the earths ozone shield followed. Let us discuss chlorofluorocarbons in detail.

One process to use up these stocks is to convert it into the fluorocarbon CH 2FCF 3 by the following route. Time by other researchers Crutzen 1974. Chlorofluorocarbons were used widely in the manufacturing industry.

One chlorofluorocarbon which was widely used as a solvent is CCl 2FCCl F 2 and large stocks of it remain.
