Physical description & handling notes

• 1,2-Dichloro-1,1,2,2-tetrafluoroethane is a colorless, nearly odorless nonflammable gas. It may be mildly toxic and irritating by inhalation. It can asphyxiate by the displacement of air. Exposure of the container to prolonged heat or fire can cause it to rupture violently and rocket. It is used as a solvent and as a fire extinguishing agent.
• Liquid
• Colorless gas with a faint, ether-like odor at high concentrations; Note: A liquid below 38 degrees F. Shipped as a liquefied compressed gas; [NIOSH]
• COLOURLESS COMPRESSED LIQUEFIED GAS.
• Colorless gas with a faint, ether-like odor at high concentrations.
• Colorless gas with a faint, ether-like odor at high concentrations. [Note: A liquid below 38 °F. Shipped as a liquefied compressed gas.]

GHS Hazard Classification

Reported hazard statements	H280 (100%), H420 (33.3%), H335, H336, H370

Documented Uses

• Used as a propellant, refrigerant, and solvent. [ACGIH]
• Mechanical vapor compression systems use fluorocarbons for refrigeration and air conditioning and account for ... majority of refrigeration capability in us. ... fluorocarbons are used as refrigerants in home appliances, mobile air conditioning units, retail food refrigeration systems & ... chillers. /Fluorocarbons/
• By treating perchloroethylene with hydrogen fluoride
• ... Obtained by treating hexachloroethane with anhydrous fluoride in the presence of small amounts of antimony chloride under high pressure.
• Chlorofluoroalkanes (and also the alternative HCFCs and HFCs) produced on an industrial scale are subject to stringent standards. Impurities must not exceed the following limits (vol %): acids, 0; moisture, <0.001; higher-boiling fractions, <0.05; and other gases, 2. /Chlorofluoroalkanes/
• For low molecular weight fluorinated hydrocarbons) 43% as aerosol propellant; 32% as refrigerant; 10% for synthesis of resins; 5% as solvent and degreaser; 4% as foam-blowing agent; 6% for misc uses including exports (1969)
