1,1-Dichloroethane Safety Profile

Moderately toxic by ingestion. Experimental teratogenic effects. Questionable carcinogen with experimental tumorigenic data. Liver damage reported in experimental animals. A very dangerous fire hazard and moderate explosion hazard when exposed to heat or flame; can react vigorously with oxidizing materials. To fight fire, use alcohol foam, water, foam, CO₂, dry chemical. When heated to decomposition it emits highly toxic fumes of phosgene and Cl⁻.

Analytical Methods:

For occupational chemical analysis use NIOSH: Hydrocarbons, Halogenated, 1003.

1,1-Dichloroethane Specification

1,1-Dichloroethane (75-34-3) is a colorless oily liquid with a chloroform-like odor. It is a chlorinated hydrocarbon and it is not easily soluble in water, but miscible with most organic solvents. It is mainly used as a feedstock in chemical synthesis, chiefly of 1,1,1-trichloroethane. and it is also used as a solvent for plastics, oils and fats, as a degreaser, as a fumigant in insecticide sprays, in halon fire extinguishers, and in cementing of rubber. It is used in manufacturing of high-vacuum resistant rubber and for extraction of temperature-sensitive substances.
