Chloroethane, or monochloroethane, is commonly known by it's old name, ethyl chloride. The chemical formula for chloroethane is C2H5Cl (subscripts). Chloroethane was once used widely in producing tetraethyllead, a gasoline additive. Chloroethane is colorless, flammable, can be a gas or refrigerated liquid, and has a slightly seet odor. The equation for the production of chloroethane is shown below:
C2H4 + HCl (subscripts) ---> C2H5Cl (subscripts)
The condensed formula would be:
H H H Cl
C = C + H-Cl ----> H - C - C - H
H H H H
Chloroethane is currently being phased out of use in gasoline production. In most industrial gasoline production, demand for chloroethan has fallen sharply. Other uses are as a refrigerant, aerosol spray propellant, anesthetic, and a blowing agent for foam packaging.
