	~~== Production ==~~		'''Trichloroethylene''' (TCE) is a [[chlorinated hydrocarbon]] commonly used as an [[industrial solvent]]. It is a clear, non-flammable liquid with a sweet smell. Trichloroethylene is used primarily in [[degreasing]] metal parts and is also found in some [[adhesives]], [[paint removers]], and [[spot removers]].
	TCE is ~~produced by chlorination of~~ [[~~ethylene~~]] ~~in the presence of~~ a ~~catalyst~~. ~~The process~~ also ~~produces~~ [[~~tetrachloroethylene~~]] ~~as a byproduct~~.

	== ~~Uses~~ ==		==History==
	~~TCE is used~~ in ~~a variety of industries for its solvent properties~~. ~~It is used~~ in the ~~manufacture of a range of products including paints, varnishes, lacquers, adhesives~~, and ~~sealants~~. ~~It is~~ also used in the ~~textile industry for dry cleaning and spot removal~~.		Trichloroethylene was first prepared in 1864 by the German chemist Emil Fischer. Its industrial use began in the 1920s, and it became widely used during [[World War II]] for degreasing metal parts. In the 1960s, trichloroethylene was also used as an [[anesthetic]] under the trade name Trilene.

	== ~~Health effects~~ ==		==Production==
	~~Exposure to TCE can have serious health effects. It has been classified as a human carcinogen~~ by the [[~~International Agency for Research on Cancer~~]] ~~and~~ the [[~~Environmental Protection Agency~~]]. ~~Long~~-~~term exposure can lead~~ to ~~liver and lung damage, and it can also affect the central nervous system~~.		Trichloroethylene is produced by the [[chlorination]] of [[ethylene]] or by the [[hydrochlorination]] of [[acetylene]]. The process involves the reaction of ethylene with chlorine to form 1,2-dichloroethane, which is then further chlorinated to produce trichloroethylene.

	== ~~Environmental impact~~ ==		==Uses==
	~~TCE~~ is a ~~persistent environmental pollutant~~. It ~~can contaminate soil~~ and ~~groundwater, and it can also evaporate into~~ the ~~air, contributing to air pollution~~.		Trichloroethylene is primarily used as a solvent for cleaning metal parts in the [[aerospace]] and [[automotive]] industries. It is also used in the production of [[hydrofluorocarbon]]s and as a chemical intermediate in the synthesis of other compounds.

	== ~~Regulation~~ ==		==Health effects==
	~~In many countries~~, ~~the use of TCE~~ is ~~heavily regulated due~~ to ~~its health~~ and ~~environmental impacts. In the United States~~, the [[~~Occupational Safety and Health Administration~~]] ~~has set limits on workplace exposure to TCE~~.		Exposure to trichloroethylene can occur through inhalation, ingestion, or skin contact. It is known to cause [[central nervous system]] depression, liver and kidney damage, and is classified as a [[carcinogen]] by the [[International Agency for Research on Cancer]] (IARC).

	== ~~See also~~ ==		==Environmental impact==
	* [[~~Chlorinated solvents~~]]		Trichloroethylene is a persistent environmental contaminant. It can be released into the air, water, and soil during its production and use. It is a common [[groundwater]] contaminant and poses a risk to human health and the environment.
	* [[Occupational safety and health]]

	== References ==		==Regulation==
	~~<references />~~		Due to its health and environmental risks, the use of trichloroethylene is regulated in many countries. The [[United States Environmental Protection Agency]] (EPA) has set limits on its concentration in drinking water and has proposed further restrictions on its use in industrial applications.

'''Trichloroethylene''' ('''TCE''') is an industrial solvent primarily used in vapor degreasing of metal parts. It is a clear non-flammable liquid with a sweet smell.

== History ==
Trichloroethylene was first prepared in 1864 by the French chemist [[Henri Victor Regnault]]. It was manufactured on a large scale during World War II as an anesthetic and a component of refrigerants.

== Production ==
TCE is produced by chlorination of [[ethylene]] in the presence of a catalyst. The process also produces [[tetrachloroethylene]] as a byproduct.

== Health effects ==
Exposure to TCE can have serious health effects. It has been classified as a human carcinogen by the [[International Agency for Research on Cancer]] and the [[Environmental Protection Agency]]. Long-term exposure can lead to liver and lung damage, and it can also affect the central nervous system.

== Environmental impact ==
TCE is a persistent environmental pollutant. It can contaminate soil and groundwater, and it can also evaporate into the air, contributing to air pollution.

== Regulation ==
In many countries, the use of TCE is heavily regulated due to its health and environmental impacts. In the United States, the [[Occupational Safety and Health Administration]] has set limits on workplace exposure to TCE.
