Trichloroethylene, chemical formula C2HCl3, is a compound formed by replacing three hydrogen atoms in an ethylene molecule with chlorine. Trichloroethylene is a flammable liquid that poses a risk of fire and explosion when exposed to open flames and high heat. Trichloroethylene has been used as an analgesic and metal degreaser, as an extractant, fungicide, refrigerant, and as a dry cleaning agent for clothes.

Function and Application

Excellent solvents used as metal surface treatment agents, cleaning agents before electroplating and painting, metal degreasers, and extractants for fats, oils, and paraffin. Used for organic synthesis and pesticide production. Trichloroethylene can be used as a anthelmintic in the production of tetrachloroethylene; Used for the production of hexachloroethane as a veterinary anthelmintic for the prevention and treatment of liver leech disease, stomach leech disease, clonorchiasis, and nematode disease in ruminants.
