CAS 811-97-2 CH2FCF3 Refrigerant Gas R134A HFC134a For Cooling Refrigerant

?

?

Description:

?

Refrigerant Gas R134A : A colorless gas with a slight ethereal odor,or cryogenic liquid with an ether-like odour.

?

Vapors are heavier than air. Vapors may cause dizziness or asphyxiation without warning. Vapors from liquefied gas are initially heavier than air and spread along ground. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating, corrosive and/or toxic gases.

?

Shipped liquefied under own vapor pressure.

?

Flash point 351°F. Inhalation at high concentrations is harmful and may cause heart irregularities, unconsciousness or death without warning.

?

Liquid contact may cause frostbite. Vapors can replace the available oxygen.

?

Some may burn but none ignite readily. Containers may explode when heated. Ruptured cylinders may rocket.

?

1,1,1,2-Tetrafluoroethane is chemically inert in many situations, but can react violently with strong reducing agents such as the very active metals and the active metals. Can react with strong oxidizing agents or weaker oxidizing agents under extremes of temperature.

?

Air & Water Reactions: Insoluble in water.

As an inert gas used primarily as a & quot;high-temperature& quot; Cooling Refrigerant and automobile air conditioners. | For domestic refrigeration and automobile air conditioners. These devices began using 1,1,1,2-tetrafluoroethane in the early 1990s as a replacement for the more environmentally harmful R-12 and retrofit kits are available to convert units that were originally R-12-equipped. Other uses include plastic foam blowing, as a cleaning solvent, a propellant for the delivery of pharmaceuticals (e.g. bronchodilators), wine cork removers, gas dusters and in air driers for removing the moisture from compressed air. 1,1,1,2-Tetrafluoroethane has also been used to cool computers in some overclocking attempts. It is also commonly used as a propellant for airsoft airguns. The gas is often mixed with a silicon-based lubricant. ? |
As inside gas duster cans | For a clear liquid which boils when exposed to atmospheric pressure at room temperature (as seen here) and can be extracted from common & quot;canned air& quot; canisters by simply inverting them during use. ? |
Being considered as an organic solvent suitable | for extraction of flavor and fragrance compounds, as a possible alternative to other organic solvents and supercritical carbon dioxide.It can also be used as a solvent in organic chemistry, both in liquid and supercritical fluid. It is used in the resistive plate chamber particle detectors in the Large Hadron Collider. It is also used for other types of particle detectors, e.g. some cryogenic particle detectors. It can be used as an alternative to sulfur hexafluoride in magnesium smelting as a shielding gas. ? |
As an alternative to sulfur hexafluoride as a dielectric gas. | Its arc-quenching properties are poor, but its dielectric properties are fairly good. ? |
