Chloroethane Chloroethane Chloroethane or monochloroethane, commonly known by its old name ethyl chloride, is a chemical compound with chemical formula , once widely used in producing tetraethyllead, a gasoline additive. It is a colorless, flammable gas or refrigerated liquid with a faintly sweet odor. Chloroethane is produced by hydrochlorination of ethene: At various times in the past, chloroethane has also been produced from ethanol and hydrochloric acid, or from ethane and chlorine, but these routes are no longer economical. Some chloroethane is generated as a byproduct of polyvinyl chloride production. Should demand for chloroethane continue to fall to the point where
Flammable liquid flash point below . This definition is part of a categorisation of "combustible liquids" used by the National Fire Protection Association, The US Department of Transportation, the US Environmental Protection Agency, the US Occupational Safety and Health Administration and others. These categories are further subdivided, depending on the liquid's flash point and boiling point. Flammable liquid Generally, a flammable liquid is a combustible liquid that can easily catch fire. However, it is not the liquid itself that burns, but the vapor cloud above the liquid that will burn if the vapor's concentration in air is between the lower flammable limit
