Uses and applications
What the substance is used for, by industry and function
Trichloroethylene is used as chemical intermediate for the production of hydrofluorocarbons (e.g., HFC134a, HFC125), monochloroacetic acid, blowing agents, flame retardants, and some agricultural chemicals. The other major use is as solvent for vapor degreasing in the metal industry. ... Trichloroethylene is further used in solvent formulations for rubbers, adhesives, industrial paints, and in the manufacture of lithium-ion batteries.

In the production of poly(vinyl chloride), it serves as a chain-transfer agent to control the molecular mass distribution.
Metal degreasing, extraction solvent for oils, fats, waxes, solvent dyeing, dry-cleaning, refrigerant and heat-exchange liquid, fumigant, cleaning and drying electronic parts, diluent in paints and adhesives, textile processing, chemical intermediate, aerospace operations (flushing liquid oxygen).
Used as household cleaner, with trichloroethane it is used in most typewriter correction fluid.
The main use of trichloroethylene is in the vapor degreasing of metal parts. Trichloroethylene is used in consumer products such as typewriter correction fluids, paint removers/strippers, adhesives, spot removers, and rug-cleaning fluids.
Industrial uses: Refrigerants, Cleaning agent, Absorbent, Laboratory chemicals, Intermediate, Solvent.

Pharmacology
Trichloroethylene is a synthetic, light sensitive, volatile, colorless, liquid that is miscible with many non-polar organic solvents. Trichloroethylene is used mainly as a degreaser for metal parts. Upon combustion, it produces irritants and toxic gases. Occupational exposure to trichloroethylene is associated with excess incidences of liver cancer, kidney cancer and non-Hodgkin lymphoma. It is reasonably anticipated to be a human carcinogen. (NCI05)
How it is made
The production of trichloroethylene is mainly based on acetylene or ethylene. The acetylene route comprises acetylene chlorination to 1,1,2,2-tetrachloroethane followed by dehydrochlorination to trichloroethylene. In the ethylene-based processes, ethylene or ethylene-based chlorohydrocarbons, preferably 1,2-dichloroethane, are chlorinated or oxychlorinated and dehydrochlorinated in the same reactor. Tetrachloroethylene is obtained as a byproduct in substantial amounts.

Some production is based on the catalytic hydrogenation of tetrachloroethylene coming from the chlorinolysis of C1 to C3 chlorohydrocarbons.
Until 1968, about 85% of United States production capacity of trichloroethylene was based on acetylene. The acetylene-based process consists of two steps: acetylene is first chlorinated to 1,1,2,2-tetrachloroethane, with a ferric chloride, phosphorus chloride or antimony chloride catalyst, and the product is then dehydrohalogenated to trichloroethylene. The current method of manufacture is from ethylene or 1,2-dichloroethane. In a process used by one plant in the United States, trichloroethylene is produced by noncatalytic chlorination of ethylene dichloride and other C2 hydrocarbons with a mixture of oxygen and chlorine or hydrogen chloride.
Prepn from sym-tetrachlorethane by elimination of (hydrochloric acid) (by boiling with lime) ..., by passing tetrachloroethane vapor over (calcium chloride) catalyst at 300 °C ..., without catalyst at 450-470 °C...
