| | 1,2-Difluorotetrachloroethane Usage And Synthesis |
| Chemical Properties | White solid or colorless liquid; slightly
camphor-like odor when concentrated. Insoluble in
water; soluble in alcohol. Nonflammable. | | Chemical Properties | Colorless liquids or solids with slight ethereal odor. | | Physical properties | Clear, colorless liquid or solid with a faint, ethereal or camphor-like odor. Evaporates quickly
when spilled. | | Uses | Degreasing solvent. | | Uses | As a refrigerant; solvent extractant; as
a blowing or foaming agent. | | 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). | | Shipping | UN1078 Refrigerant gases, n.o.s., Hazard Class: 2.2; Labels: 2.2-Nonflammable compressed gas, Technical Name Required | | Incompatibilities | Acids and chemically active metals, such as potassium, beryllium, powdered aluminum; zinc, calcium, magnesium, and sodium. |
