1,1,1,2-Tetrafluoroethane[edit | edit source]
Introduction[edit | edit source]
1,1,1,2-Tetrafluoroethane, commonly known by several names including R-134a, Freon 134a, and HFC-134a, is a hydrofluorocarbon (HFC) used primarily as a refrigerant. It is known for having thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with significantly lower environmental impact.
Chemical Properties[edit | edit source]
The chemical formula for 1,1,1,2-Tetrafluoroethane is CF3CH2F. It has a boiling point of −26.3 °C (−15.34 °F) at atmospheric pressure.
Environmental Impact[edit | edit source]
R-134a is notable for its negligible ozone depletion potential and a lower 100-year global warming potential (GWP) of 1,430, compared to R-12's GWP of 10,900.
Uses[edit | edit source]
This compound is used in various applications such as:
- Automotive air conditioning systems
- Refrigeration systems
- Aerosol propellants
- Foam-blowing agents
Health and Safety[edit | edit source]
Exposure to R-134a can have health implications, including skin and eye irritation and, in high concentrations, asphyxiation.
Regulation and Phaseout[edit | edit source]
Due to environmental concerns, there has been a move to phase out R-134a since 2012, particularly in the automotive market. Alternatives like HFO-1234yf, with GWPs similar to CO2, are being adopted.
Container Identification[edit | edit source]
R-134a cylinders are identified by their light blue color.
Transition to Alternatives[edit | edit source]
The transition to more environmentally friendly alternatives, such as HFO-1234yf, is ongoing in response to environmental regulations and concerns over global warming.
