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. [ 5 ] CFC-11 is a Class 1 ozone -depleting substance which damages Earth's protective stratospheric ozone layer. [ 6 ]
'Freon' is the brand name for the refrigerants R-12, R-13B1, R-22, R-410A, R-502, and R-503 manufactured by The Chemours Company, and so is not used to label all refrigerants of this type. They emit a strong smell similar to acetone. [2] Freon has been found to cause damage to human health when inhaled in large amounts.

Infobox references. 1,1,2-Trichloro-1,2,2-trifluoroethane, also called trichlorotrifluoroethane (often abbreviated as TCTFE) or CFC-113, is a chlorofluorocarbon. It has the formula Cl2FC−CClF2. This colorless, volatile liquid is a versatile solvent.
1,2-Dichlorotetrafluoroethane, or R-114, also known as cryofluorane (INN), is a chlorofluorocarbon (CFC) with the molecular formula ClF 2 CCF 2 Cl. 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.
Overview. The Synthex was conceived and developed by independent Italian designer Mario Maggi, who then gained the financial backing of the Elka company of Italy, who produced the synthesizer from 1981 to 1985. Elka, a company more noted for its organs, had previously introduced their Rhapsody 490, 610 string machine, the monophonic Solist 505 ...
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 propellant. In compliance with the Montreal Protocol, its manufacture was banned in developed countries (non-article 5 countries) in 1996, and in developing countries ...
They also released a keyboard-less version of the Chroma called the Chroma Expander at a list price of US $3150. [3] The Chroma was one of the early microprocessor-controlled analog synthesizers. It was designed before MIDI and featured a 25-pin D-sub connector computer interface used to slave the Expander to the Chroma.
