Descripción

General description

Trichloroethylene (TCE) is a halocarbon commonly used as an industrial chlorinated solvent. It can also be used as an intermediate in the production of other chemicals and refrigerants.

Application

Trichloroethylene can be used:

• As a solvent in the C- and O-glycosylation reactions of tetrahydropyran acetals and 2-deoxyglucopyranosides to prepare SN₂ products.
• In the chemical industry for the synthesis of polyvinyl chloride, chloroacetic acid, hydrofluorocarbons, pharmaceuticals, insecticides, fungicides, fire retardants, fertilizer, and synthetic rubber.
• As a starting material in the synthesis of dichloroacetylene.
• As a reagent in the preparation of alkynic ethers.
• As a reagent for ethynylation and vinylation process.
