ʻO Trichlorethylene (TCE) he wai ʻawaʻawa kūpaʻa me ka ʻala like me ka chloroform (ATSDR, 2011).Hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i loko o nā momona a me nā mea hoʻoheheʻe kūlohelohe maʻamau, a hoʻolapalapa ʻia ma 87°C (190 F).
Ke hoʻopili ʻia me ka ea, hoʻoheheʻe mālie ʻia a hana i ka phosgene, hydrogen chloride, a me dichloroacetyl chloride.ʻO ka Trichlorethylene e pili ana me ka wai, lilo ia i mea ʻino a hoʻohua i ka waikawa dichloroacetic a me ka waikawa hydrochloric.Hiki ke hoʻoheheʻe ʻia i ka methanol, diethyl ether, a me ka acetone.
Ua ʻike ʻia ʻo Trichlorethylene he trichloroethene, acetylene trichloride, 1-chloro-2,2- dichloroethylene, a me ethylene trichloride, a ua hoʻopau pinepine ʻia ʻo ia i TRI.He mea hoʻoheheʻe ia, chlorinated organic hydrocarbon i hoʻohana nui ʻia no ka hoʻoheheʻe ʻana i nā metala a ma ke ʻano he hydrofluorocarbon (HFC-134a) waena (ATSDR, 2013).Hoʻohana ʻia ia i loko o nā mea hoʻopili, nā mea hoʻonaninani pena, nā pena, nā lacquers, a me nā varnish.I nā makahiki 1930, ua hoʻokomo ʻia ʻo TCE no ka hoʻohana ʻana i ka hoʻomaʻemaʻe maloʻo, akā ua hoʻopau nui ʻia kēia hana i ka makahiki 1950 i ka wā i pani ʻia ai ʻo TCE e tetrachlorethylene (PCE).Loaʻa iā ia kekahi mau mea i hoʻohana mua ʻia i nā mea hoʻonaninani, nā lāʻau lapaʻau, nā meaʻai, a me nā pesticides (US EPA, 2011).He mea hoʻohaumia kaiapuni i ʻike ʻia ma ka ea, ka wai lepo, ka wai ʻili, a me ka lepo
