Product Description

Tetrachloroethylene CAS#127-18-4

Tetrachloroethylene is a chlorinated hydrocarbon with the molecular formula Cl₂C=CCl₂, widely used as an industrial solvent and as a cooling and insulating liquid in electrical transformers. It appears as a colorless, volatile liquid with a mild ether-like odor and is nonflammable, providing enhanced safety in industrial environments.

Most tetrachloroethylene is produced through high-temperature chlorinolysis of light hydrocarbons, ensuring stable supply and consistent product quality for large-scale industrial applications.


Product Application of Tetrachloroethylene CAS#127-18-4

Tetrachloroethylene (PCE) is also known as perchloroethylene, tetrachloroethene, and 1,1,2,2- tetrachloroethene and is also commonly abbreviated to PER or PERC. Tetrachloroethylene is a volatile, chlorinated organic hydrocarbon that is widely used as a solvent in the dry-cleaning and textile-processing industries and as an agent for degreasing metal parts. It is an environmental contaminant that has been detected in the air, groundwater, surface waters, and soil (NRC, 2010).
