Brief Introduction to Difluoroethane

Difluoroethane is an organofluorine compound with the chemical formula C2H4F2. This colorless gas is used as a refrigerant, where it is often listed as R-152a (refrigerant-152a) or HFC-152a (hydrofluorocarbon-152a). It is also used as a propellant for aerosol sprays and in gas duster products. As an alternative to chlorofluorocarbons, it has an ozone depletion potential of zero, a lower global warming potential (124) and a shorter atmospheric lifetime (1.4 years). It has many other names (synonyms), including:

Difluoroethane Chemical Basic Information

Chemical Properties: liquefied colourless gas under pressure.

Chemical Properties: Difluoroethane is a liquefied gas and exists as a liquid at room temperature when contained under its own vapor pressure, or as a gas when exposed to room temperature and atmospheric pressure. The liquid is practically odorless and colorless. Difluoroethane is noncorrosive and nonirritating.

Uses: HFC 152a is a specialty liquified hydrofluorocarbon gas. It is used as an intermediate in the production of fluorinated polymers, as an aerosol propellant in some specialty applications, and as a component in some refrigerant blends.

Production Methods: Difluoroethane is prepared from ethyne by the addition of hydrogen fluoride in the presence of a suitable catalyst. The difluoroethane formed is purified to remove all traces of water, as well as traces of the starting materials.

General Description: Difluoroethane is colorless, odorless gas shipped as a liquefied gas under its vapor pressure. Contact with the liquid can cause frostbite. Difluoroethane is easily ignited. Its vapors are heavier than air and a flame can travel back to the source of leak very easily. This leak can be either a liquid or vapor leak. Difluoroethane can asphyxiate by the displacement of air. Under prolonged exposure to fire or heat the containers may rupture violently and rocket.

Air & Water Reactions: Highly flammable.

Reactivity Profile: Halogenated aliphatic compounds, such as Difluoroethane, are moderately or very reactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Low molecular weight haloalkanes are highly flammable and can react with some metals to form dangerous products. Materials in this group are incompatible with strong oxidizing and reducing agents. Also, they are incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides. The reaction of aluminum with various halogenated hydrocarbons produces a self-sustaining reaction with sufficient heat to melt aluminum pieces, examples of other halogenated hydrocarbons are fluorotrichloromethane, dichlorodifluoromethane, chlorodifluoromethane, tetrafluoromethane. The vigor of the reaction appears to be dependent on the combined degree of fluorination and the vapor pressure.

Health Hazard: Inhalation of concentrated gas will cause suffocation. Contact with liquid can damage eyes because of low temperature. Frostbite may result from contact with liquid.

Pharmaceutical Applications: Difluoroethane, a hydrofluorocarbon (HFC), is an aerosol propellant used in topical pharmaceutical formulations. Difluoroethane may be used as a vehicle for dispersions and emulsions.
Since difluoroethane does not contain chlorine, there are no environmental controls on the use of this material as a propellant, since it does not deplete the ozone layer and is not a greenhouse gas.

Safety Profile: Mildly toxic by inhalation. Mutation data reported. Narcotic in high concentration. A very dangerous fire hazard when exposed to heat or flame; can react vigorously with oxidzing materials. See also FLUORIDES.

Hazards and Protection

Storage

Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.

Handling

All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.

Protection

Employees should be provided with and required to use impervious clothing, gloves, face shields (8-in minimum), and other appropriate protective clothing necessary to prevent repeated or prolonged skin contact with liquid or solid. Employees should be provided with and required to use dust- and splash-proof safety goggles where liquid or solid may contact the eyes. Wear appropriate eye protection and protective clothing.

Respirators

Any self-contained breathing apparatus that has a full facepiece and is operated in a pressure-demand or other positive pressure mode. Any supplied-air respirator that has a full facepiece and is operated in pressure-demand or other positive pressure mode in combination with an auxiliary self-contained breathing apparatus operated in pressure-demand or other positive pressure mode. Any appropriate escape-type, self-contained breathing apparatus.

Small Spills/Leaks

Evacuate area and ventilate. Wear protective equipment. If required, use an inert absrobent. Sweep up and place in an appropriate container for disposal. Wash contaminated surfaces.

Stability

No data.

Incompatibilities

Reacts with chemically active metals such as sodium, potassium, beryllium, or with powdered aluminum, zinc, and magnesium.

Decomposition

When heated to decomposition it emits toxic fumes of flourides and chlorides. Toxic gases and vapors (such as hydrogen chloride, hydrogen fluoride, carbon monoxide) may be released when 1,1,2,2-tetrachloro-1,2-difluoroethane decomposes. Appearance of toxic decomposition products serves as warning of occurrence of thermal decomposition and detection of sharp acrid odor warns of presence.

Ultimate FAQ Guide to Difluoroethane

Q: Why do people inhale difluoroethane?

A: Inhalants are often abused due to their ability to acutely induce feelings of euphoria. Difluoroethane is a toxic lipophilic hydrocarbon that crosses the blood-brain barrier and inhibits the central nervous system. Studies have shown the cardiac, renal, and respiratory effects it has when abused.

Q: How much difluoroethane is lethal?

A: The decedent's blood was positive for 1,1-difluoroethane (DFE) (52 mcg/mL) and mitragynine (18 ng/mL). Documented deaths associated with DFE abuses have reported in postmortem blood concentrations as low as 29 µg/mL. DFE is an organofluorine compound that is a colorless gas.

Q: Is difluoroethane bad for you?

A: Rapid evaporation of the liquid may cause frostbite. The substance may cause effects on the cardiovascular system. This may result in cardiac disorders. Exposure at high levels could cause unconsciousness.

Q: What chemical gets you high in air duster?

A: Compressed air duster cans currently available in the USA contain highly toxic substances including different hydrofluorocarbons (including tetrafluoroethane and difluoroethane) which exert a psychoactive effect on the central nervous system.

Q: Does difluoroethane make you high?

A: DFE is a central nervous system (CNS) depressant associated with a brief sensation of euphoria when inhaled. Prolonged or excessive use is associated with toxicity, and abrupt cessation can induce withdrawal.

Q: What happens if you accidentally inhale air duster?

A: When someone inhales air duster, it causes a depression of oxygen levels as the fumes go into the lungs and then the central nervous system. This can make it impossible for the person to breathe; therefore, they suffocate. Also possible is something called sudden sniffing death.

Q: Is difluoroethane a carcinogen?

A: 1 ,l -Difluoroethane is practically non-toxic following acute or chronic inhalation exposures. It is not a developmental or reproductive toxicant in rat studies and is negative for cancer in a two year rat inhalation study. It is not mutagenic in a in vitro bacterial reverse mutation assay and shows some weak clastogenicity in an in vitro human lymphocyte chromosome aberration test, but further evaluation of its ability to cause chromosome damage in and in vivo micronucleus test was negative. There is evidence that 1,1-difluoroethane can cause cardiac effects is some species, most notably heart arrhythmia in the dog.

Q: What is difluoroethane made of?
