Tri chloroethylene, also known as trichloroethylene or TCE, is a volatile organic compound with the chemical formula C2HCl3. It is a colorless, non-flammable liquid with a sweet odor and is widely used as an industrial solvent. Tri chloroethylene is valued for its degreasing and cleaning properties and is commonly employed in metalworking, electronics manufacturing, and aerospace industries. It is effective in removing grease, oils, and other contaminants from metal parts and electronic components. However, it is important to note that TCE is considered a hazardous air pollutant and poses health risks to humans, so its use is subject to strict regulations and safety measures.

Despite its effectiveness as a solvent, the use of tri chloroethylene has declined in recent years due to increasing environmental and health concerns. Exposure to TCE has been linked to various health issues, including respiratory problems, neurological effects, and potential carcinogenicity. Consequently, many industries have sought alternative, safer solvents and cleaning methods. As regulations become stricter and awareness of the risks associated with TCE grows, companies are transitioning to more sustainable and environmentally friendly practices to protect both workers and the environment.
