Which is the correct formula of Freon 12?
CCl2F2
Dichlorodifluoromethane/Formula
What is the correct chemical formula for 12 dichloro tetra fluoro ethane?
1,2-Dichlorotetrafluoroethane, or R-114, also known as cryofluorane (INN), is a chlorofluorocarbon (CFC) with the molecular formula ClF2CCF2Cl. Its primary use has been as a refrigerant. It is a non-flammable gas with a sweetish, chloroform-like odor with the critical point occurring at 145.6 °C and 3.26 MPa.
What is R718 refrigerant?
Abstract. Even though water (R718) is one of the oldest refrigerants, state of the art technology is required to use water as a refrigerant in compression refrigeration plants with turbo compressors. Because the cycle works at very low pressure, the volumetric cooling capacity of water vapor is very low.
What is the formula of chlorofluorocarbon?
Numbering system
| hidePrincipal CFCs | ||
|---|---|---|
| Systematic name | Common/trivial name(s), code | Formula |
| Trichlorofluoromethane | Freon-11, R-11, CFC-11 | CCl3F |
| Dichlorodifluoromethane | Freon-12, R-12, CFC-12 | CCl2F2 |
| Chlorotrifluoromethane | Freon-13, R-13, CFC-13 | CClF3 |
How do you make Freon-12?
It can be prepared by reacting carbon tetrachloride with hydrogen fluoride in the presence of a catalytic amount of antimony pentachloride: CCl4 + 2HF → CCl2F2 + 2HCl.
Is R12 Freon illegal?
R-12 is a colorless and odorless CFC refrigerant that was completely banned from production by 1996 under the Montreal Protocol for depleting the ozone. R-12 has many applications in refrigeration and air conditioning including large to mediums size chillers, automotive air conditioning, and as an aerosol propellant.
Which Freon is used as refrigerant?
Freon-12 CCl2F2 is widely used as a refrigerant (cooling agent) in refrigerators and air conditioners.
Is R718 flammable?
R718 is an excellent refrigerant. It is an environmentally safe (ODP=0 and GWP=0), non- toxic, non-flammable, non-explosive, easy available, and the cheapest refrigerant. It has also the highest COP at higher evaporator temperatures.
What is R11?
Refrigerant R-11 is another refrigerant used commonly in the refrigeration and air conditioning systems. The chemical name of R11 is trichloromonofluoromethane (it is methane series compound) and its chemical formula is CCl3F. R-11 refrigerant is also used as the solvent and the secondary refrigerant.
What do you call a compound that is a refrigerant?
Compounds used as refrigerants may be described using either the appropriate prefix above or with the prefixes “R-” or “Refrigerant.” Thus, CFC-12 may also be written as R-12 or Refrigerant 12. An alkene, olefin, or olefine is an unsaturated chemical compound containing at least one carbon -to- carbon double bond.
Can a CFC be written as a refrigerant?
Thus, CFC-12 may also be written as R-12 or Refrigerant 12. An alkene, olefin, or olefine is an unsaturated compound containing at least one carbon-carbon double bond. ^ a b c d e Some CFCs are assumed to be similar in terms of Semi-Empirical ODP being one.
Which is refrigerant is used for direct contact freezing?
Dichlorodifluoromethane is a direct contact freezing agent for foods. Refrigerant, aerosol propellant Dichlorodifluoromethane (R-12), usually sold under the brand name Freon-12, is a chlorofluorocarbon halomethane (CFC), used as a refrigerant and aerosol spray propellant.
