Trichloroethylene (TCE) CAS 79-01-6 Molecular formula C2HCl3 is a colorless, slightly sweet volatile liquid and a highly soluble solvent. It is insoluble in water but soluble in organic solvents such as ethanol and ether. It is non-flammable under normal conditions. Due to its moderate boiling point, high vapor pressure, strong stability, and suitability for gas washing operations, it is used in industry for metal cleaning (thorough degreasing) and fiber degreasing.
Common Synonyms:
- Ethylene trichloride
- Trichloroethene
- 1,1,2-Trichloroethylene
- Triclene
Is Trichloroethylene CAS 79-01-6 Banned or Restricted?
Trichloroethylene is NOT completely banned worldwide ,but it is heavily restricted and effectively banned in the U.S.
Regulations by Region
🇪🇺 European Union (EU)
The use of trichloroethylene (TCE) is restricted and requires official approval, in accordance with the REACH regulation. Most consumer uses are prohibited. Industrial uses are permitted only under strict safety controls. In effect, TCE has been largely phased out in the EU.
🇺🇸 United States
The U.S. Environmental Protection Agency (EPA) regulates TCE under the Toxic Substances Control Act. Certain uses, such as aerosol degreasers, have been banned or are under review. Workplace exposure limits for TCE are clearly defined. Overall, regulations are becoming increasingly stringent, and TCE usage is gradually decreasing.
🇨🇳 China
TCE is still permitted for industrial use. Users must comply with national chemical safety regulations. TCE is managed as a hazardous chemical. Under strict official control, TCE is widely used in China.
Restricted Applications of Trichloroethylene TCE
In many regions, the following uses are banned or limited:
- Consumer products (cleaners, aerosols)
- Dry cleaning (replaced by alternatives like PCE)
- Open-use degreasing without vapor control
- Household applications
Where Is Trichloroethylene TCE solvent Still Used?
Despite the restrictions, trichloroethylene solvent is still used in closed industrial degreasing, chemical intermediate production, and special manufacturing processes, all of which require strict safety and emission controls.
