Product details

CAS No.79-01-6

Category	Details
Chemical Name	Trichloroethylene
Abbreviation	TCE
CAS Number	79-01-6
Chemical Formula	C2HCl3
Molecular Weight	131.39 g/mol
Appearance	Colorless transparent liquid with a characteristic odor similar to chloroform
Physical Properties	Density: 1.46 g/cm³; Boiling Point: 87.1°C; Soluble in organic solvents such as ethanol, ether, acetone, carbon tetrachloride, and chloroform; Slightly soluble in water; Volatile and flammable at higher temperatures; Vapor can form explosive mixtures with air
Chemical Stability	Unstable; Oxidizes in air to produce phosgene, carbon monoxide, and hydrogen chloride without stabilizers; Resistant to most metals at ordinary temperatures, but reacts with acids, water, and metal powders under certain conditions
Production Methods	Prepared from acetylene, with tetrachloroethane as a diluent and anhydrous ferric chloride as a catalyst; Alternatively, ethylene and chlorine are passed into a reaction tower to produce a mixture of tetrachloroethane and pentachloroethane, which is then cracked in the presence of a barium chloride catalyst on activated carbon to produce trichloroethylene and tetrachloroethylene
Applications	Used as a degreaser for metals, a solvent, and an extractant in industries such as electroplating, electrical machinery, medicine, and dry cleaning; Also used as an anesthetic and in the production of tetrachloroethylene for anthelmintic drugs
Storage Conditions	Store in a cool, well-ventilated, dry warehouse; Keep in a sealed container and avoid sunlight; Store separately from food chemicals and strong alkalis; Keep away from heat sources
Health Hazards	Inhibits the central nervous system, leading to general anesthesia; Long-term exposure may cause organic damage; Causes dermatitis upon skin contact; Causes mild irritation and tearing when in contact with eyes
