Chloroethane, commonly known as ethyl chloride, is a chemical compound with chemical formula CH 3 CH 2 Cl, once widely used in producing tetraethyllead, a gasoline additive. It is a colorless, flammable gas or refrigerated liquid with a faintly sweet odor.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

In the laboratory it is occasionally used as a source of chlorine, with elimination of ethene and chloride. Via several steps, 1,2-dichloroethane is a precursor to 1,1,1-trichloroethane . Historically, before leaded petrol was phased out, chloroethanes were used as an additive in petrol to prevent lead buildup in engines.
The 1,1,2,2-tetrachloroethane is then dehydrochlorinated to give trichloroethylene. This can be accomplished either with an aqueous solution of calcium hydroxide: 2 Cl 2 CHCHCl 2 + Ca(OH) 2 → 2 ClCH=CCl 2 + CaCl 2 + 2 H 2 O. or in the vapor phase by heating it to 300–500 °C on a barium chloride or calcium chloride catalyst: Cl 2 CHCHCl 2 ...
Ethylene chloride is a chemical name that can refer to either of the following compounds: 1,2-dichloroethane: formula C 2 H 4 Cl 2: vinyl chloride: formula C 2 H 3 Cl
