'''1,1-Dichloroethane''' is a [[chlorinated hydrocarbon]].  It is a colorless [[viscosity|oily]] liquid with a [[chloroform]]-like odor.  It is not easily soluble in water, but miscible with most organic solvents.

Large volumes of 1,1-dichloroethane are manufactured, with annual production exceeding 1 million pounds in the United States. It is mainly used as a feedstock in chemical synthesis, chiefly of [[1,1,1-Trichloroethane|1,1,1-trichloroethane]]. It is also used as a [[solvent]] for [[plastic]]s, [[oil]]s and [[fat]]s, as a [[degreaser]], as a [[fumigant]] in [[insecticide]] sprays, in [[halon]] [[fire extinguisher]]s, and in cementing of [[rubber]]. It is used in manufacturing of high-[[vacuum]] resistant rubber and for [[solvent extraction|extraction]] of temperature-sensitive substances.  Thermal [[cracking (chemistry)|cracking]] at 400-500 °C and 10 MPa yields [[vinyl chloride]].  In the past, 1,1-dichloroethane was used as a surgical [[inhalational anesthetic]].

In the atmosphere, 1,1-dichloroethane decomposes with half-life of 62 days, chiefly by reaction of [[photolysis|photolytically]] produced [[hydroxyl]] [[radical (chemistry)|radicals]].
