HCFC-123 is used in large tonnage centrifugal chiller applications, and is the most efficient refrigerant currently in use in the marketplace for HVAC applications. HCFC-123 is also used as a testing agent for bypass leakage of carbon adsorbers in gas filtration systems, and as the primary chemical in Halotron I fire-extinguishing agent. [2]
Halotron I is a fire extinguishing agent primarily composed of a raw material HCFC-123 (93%), mixed with tetrafluoromethane and argon serving as propellants. Global emission concerns [ edit ]
A special numbering system is to be used for fluorinated alkanes, prefixed with Freon-, R-, CFC- and HCFC-, where the rightmost value indicates the number of fluorine atoms, the next value to the left is the number of hydrogen atoms plus 1, and the next value to the left is the number of carbon atoms less one (zeroes are not stated), and the ...
R-22 HCFC-22: CHClF 2: Chlorodifluoromethane: 5280: 1760: Being phased out: A widely used hydrochlorofluorocarbon (HCFC) and powerful greenhouse gas with a GWP equal to 1810. Worldwide production of R-22 in 2008 was about 800 Gg per year, up from about 450 Gg per year in 1998. R-438A (MO-99) is a R-22 replacement. [71] R-123 HCFC-123 CHCl 2 CF 3

The cat (Martha Stewart’s fitness routine) is out of the bag. The lifestyle mogul recently had a chat with Pamela Anderson for Elle and let slip that she does Pilates three mornings a week.. The ...
It can form by the elimination of HCl or HF from other HCFCs like HCFC-133a. CF 3 CH 2 Cl → CF 2 =CHCl + HF. It can be removed from the mixture by various physical processes such as absorption, or chemical processes, that fluorinate, reduce or oxidise it. [7] An example specification for medical use of HFC-134a requires under 5 ppm of HCFC ...
