The chloro fluoro derivatives of methane and ethane are called freons. Some of the derivatives are: CHF2Cl (monochlorodifluoromethane), CF2Cl2 (dichlorodifluoro-methane), HCF2CHCl2 (1,1-dichloro-2,2-difluoroethane). These derivatives are non-inflammable, colourless, non-toxic, low boiling liquids. These are stable upto 550°C. The most important and useful derivative is CF2Cl2 which is commonly known as freon and freon-12.
Freon or freon-12 (CF2Cl2) is prepared by treating carbon tetrachloride with antimony trifluoride in the presence of antimony pentachloride as a catalyst.
(SbCl5).
3CCl4 + 2SbF3 -----→ 3CCl2F2 + 2SbCl3
Catalyst
Or it can be obtained by reacting carbon tetrachloride with hydrofluoric acid in presence of antimony pentachloride (SbCl5).
CCl4 + 2HF -----→ CCl2F2 + 2HCl
Under ordinary conditions freon is a gas. Its boiling point is -29.8°C. It can easily be liquified. It is chemically inert. It is used in air-conditioning and in domestic refrigerators for cooling purposes (As refrigerant). It causes depletion of ozone layer.
Dimedone is synthesized from mesityl oxide and diethyl malonate .
It is the ribosome. Proteins are synthesized on that
Components are synthesized in nucleolus.They are combined in cytoplasm.
The refrigerant that replaced Freon in refrigerators is called HFC-134a.
Freon under pressure, much like LP and butane are liquid. At sea level pressure, freon becomes a gas. For freon to work in a refrigeration system, it must be able to transform from liquid to gas to liquid. So, to fill a system, it must be put into that system in liquid form. To do this, the bottle containing freon must be tipped, otherwise only freon the gas would be expelled.
Is r-22 Freon compatible with r-134a freon?
It is synthesized in the cytoplasm by the process of translation.
Dimedone is synthesized from mesityl oxide and diethyl malonate .
They are the only plasma proteins that are not synthesized in liver, but are synthesized in lymph nodes .
DNA is synthesized in a 5' to 3' direction.
Contains no Freon. Freon was banned beginning in 1996.
Yes, bile acids are synthesized in the liver.
Another word for synthesized is amalgamated or integrated.
Dimedone is synthesized from mesityl oxide and diethyl malonate .
Freon is DuPont's trade name. There are 2 types of Freon, Freon-11 is trichlorofluoromethane, while Freon-12 is dichlorodifluoromethane. All types of Freon have been banned from production since 1996. Refrigerants are manmade compounds not Elements
NO
When the fridge is not cooling due to freon leak or freon restriction.
