Mar 30, 2026 Leave a message

Yes, CAS 79-01-6 trichloroethylene (TCE) is highly dangerous to humans and is classified as a known human carcinogen. It is a volatile organic compound used mainly in industrial degreasing.

 

Use of Trichloroethylene

  1. Trichloroethylene TCE is used in the manufacture of various fluorocarbon refrigerants.
  2. As an efficient degreaser, TCE was used for machinery parts and equipment. It is used to extract grease from fabricated pieces of metal and certain textiles as a solvent (trichloroethylene solvent).
  3. TCE has also been used to clean kerosene-fueled rocket engines (trichloroethylene military use).
  4. It is also used in adhesives, paint removers, fluids for typewriter correction, and spot removers as an ingredient.
  5. Used for the production of 100% ethanol by removing residual water.

Health Risks of TCE Trichloroethylene solvent

1. Acute Exposure

  • Inhalation: Dizziness, headache, nausea, confusion
  • Skin contact: Irritation, redness, or dermatitis
  • Eye contact: Irritation, tearing

2. Chronic Exposure

  • Liver damage: Hepatotoxicity with long-term exposure
  • Kidney damage: Nephrotoxicity reported in industrial workers
  • Neurological effects: Memory loss, concentration problems, peripheral neuropathy

 

Safety & Handling

Trichloroethylene TCE requires careful handling due to its toxicological properties. While it has no flash point under normal conditions, it has an autoignition temperature of 410°C. Always use appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection. Ensure adequate ventilation to prevent vapor accumulation, as TCE has a vapor density of 4.53 times that of air and can accumulate in low-lying areas.
