Usage And Synthesis

Chemical Properties

Colorless liquids or solids with slight ethereal odor.

Chemical Properties

White solid or colorless liquid; slightly camphor-like odor when concentrated. Insoluble in water; soluble in alcohol. Nonflammable.

Physical properties

Clear, colorless liquid or solid with a faint, ethereal or camphor-like odor. Evaporates quickly when spilled.

Uses

As a refrigerant; solvent extractant; as a blowing or foaming agent.

Uses

Degreasing solvent.

General Description

Colorless low-melting solid or liquid with a slight ethereal odor. Mp: 26.5°C; bp: 92.5°C. Density (of liquid): 1.64 g cm-3 at 30°C. Used as a refrigerant, a solvent extractant, and in dry cleaning.

Reactivity Profile

1,2-DIFLUOROTETRACHLOROETHANE is non-flammable. Incompatible with active metals such as potassium, sodium, beryllium, powdered aluminum, zinc, magnesium, and calcium. Reacts with acids.

Hazard

Toxic by inhalation.

Health Hazard

At high concentrations, 1,1,2,2- tetrachloro-1,2-difluoroethane affects the nervous system and causes pulmonary edema in animals; it is expected that severe exposure in humans will produce the same effects. There are no reports of adverse effects in humans.

Safety Profile

A poison by inhalation. Moderately toxic by ingestion. A sktn and eye irritant. When heated to decomposition it emits toxic fumes of Fand Cl-. See also CHLORINATED HYDROCARBONS, ALIPHATIC; and FLUORIDES.

Potential Exposure

Possible risk of forming tumors, Primary irritant (w/o allergic reaction).
