Tetrachloroethylene, also known as perchloroethylene [a] or under the systematic name tetrachloroethene, and abbreviations such as perc (or PERC), and PCE, is a chlorocarbon with the formula Cl 2 C=CCl 2. It is a non-flammable, stable, colorless and heavy liquid widely used for dry cleaning of fabrics.

Tetrachloroethylene oxide, perchloroethylene oxide (PCEO) or tetrachlorooxirane, is the perchlorinated analogue of ethylene oxide and a proposed metabolite of tetrachloroethylene. [3] It is a halogenated epoxide with the formula C 2 Cl 4 O. Tetrachloroethylene oxide is fairly stable but rearranges to trichloroacetyl chloride at higher ...

Trichloroethylene (TCE) is a halocarbon with the formula C 2 HCl 3, commonly used as an industrial metal degreasing solvent.It is a clear, colourless, non-flammable, volatile liquid with a chloroform-like pleasant mild smell [3] and sweet taste. [9]
The density of perchloroethylene is around 1.62 g/cm 3 at room temperature (62% heavier than water), and the sheer weight of absorbed solvent may cause the textile to fail under typical forces during the spin extraction cycle, unless the mesh bag provides mechanical support. Not all stains can be removed by dry cleaning. Some need to be treated ...
Brake cleaner in different containers. Brake cleaner, often also called parts cleaner, is a mostly colorless cleaning agent, mainly used for cleaning the brake disks, the engine compartment and underfloor of motor vehicles.
Haloalkenes have also been used as solvents, including perchloroethylene (Perc, tetrachloroethene), widespread in dry cleaning, and trichloroethylene (TCE, 1,1,2-trichloroethene). Other haloalkenes have been chemical building blocks of plastics such as polyvinyl chloride ("vinyl" or PVC, polymerized chloroethene) and Teflon ( duPont trademark ...
