What is 1 1 1 2 Tetrafluoroethane? Tel：+86-592-5803997
1 1 1 2 Tetrafluoroethane, with the chemical formula cf3ch2f and CAS number 811 97 2, is also commonly known as HFA 134a, Norflurane, or R134a. This colorless gas has emerged as a significant chemical compound in various industries due to its unique properties.
Chemical and Physical Properties
1,1,1,2 - Tetrafluoroethane has a molar mass of approximately 102.03 g/mol. It is a non - flammable gas, which is a crucial safety feature in many of its applications. At atmospheric pressure, it has a boiling point of - 26.3 °C (- 15.34 °F), allowing it to easily transition between gaseous and liquid states under typical environmental conditions. Its density in the gaseous form is around 0.00425 g/cm³. The melting point of 1,1,1,2 - tetrafluoroethane is - 103.3 °C (- 153.9 °F or 169.8 K). These physical properties make it suitable for a wide range of applications, especially those that require a substance with stable thermodynamic characteristics.
How Is 1 1 1 2 Tetrafluoroethane work as Aerosol Propellant?
Purity over 99.99% 1 1 1 2 Tetrafluoroethane functions as an aerosol propellant by leveraging its phase change properties and vapor pressure. In an aerosol container, which is typically a sealed metal or plastic can, 1,1,1,2 tetrafluoroethane exists in both liquid and gaseous states in equilibrium. When the valve on the aerosol can is depressed, the pressure inside the can is released, disrupting the equilibrium. The liquid 1,1,1,2 tetrafluoroethane rapidly vaporizes due to the drop in pressure, creating a high - pressure gas stream. This gas stream forces the product inside the can, such as a liquid medication, paint, or cleaning solution, out through a small orifice in the valve. As the product exits the can, it mixes with the gas propellant, atomizing into a fine mist or spray. The key to this process is the low boiling point of 1,1,1,2 tetrafluoroethane (-26.3 °C), which allows it to quickly change from a liquid to a gas under the slight pressure reduction when the valve is opened, generating the necessary force to propel the product.
Advantages OF 1 1 1 2 Tetrafluoroethane As propellant In pharmaceutical aerosols
Tel：+86-592-5803997
Good chemical stability: HFA134a propellant is not easy to react chemically with drug ingredients, which can ensure the stability of aerosol drugs during storage and use, and ensure the quality and efficacy of drugs.
Good projectile performance: aerosol propellant gases HFA 134a's vapor pressure is moderate and can provide stable pressure, so that the drugs in aerosol products can be sprayed evenly and accurately, achieving a good atomization effect, which is convenient for patients to use and drug absorption.
Environmentally friendly: Compared with traditional chlorofluorocarbon (CFC) propellants, HFA 134A as propellants in aerosol cans has no destructive effect on the ozone layer, meets environmental protection requirements, and is a more ideal alternative product.
