Products Description of Trichloroethylene CAS# 79-01-6

Trichloroethylene (TCE), also known as trichloroacetylide, 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.
