Product Details

Tetrachloroethylene CAS#127-18-4

Tetrachloroethylene (chemical method Cl2C=CCl2) is a chlorinate hydrocarbon used as an industrial solvent and cooling liquid in electrical transformers. It is a colorless, volatile, nonflammable liquid with an ether-like odor. The most important section of tetrachloroethylene is produced by means of excessive temperature chlorinolysis of mild hydrocarbons.
Tetrachloroethylene is an awesome solvent for natural materials. It is volatile, quite stable, and nonflammable, and for this reason being extensively used in dry cleaning. It can additionally be used to degrease steel components in the car and different metalworking industries upon being combined with different chlorocarbons. It can additionally be used in neutrino detectors. However, it ought to be stated that it is a conceivable carcinogen.

Product Usage

Tetrachloroethylene is used as a solvent, indrycleaning, and in metallic degreasing.Tetrachloroethylene is a frequent industrial solvent that is frequently observed as a contaminant in groundwater. Tetrachloroethylene is additionally a suspected carcinogen to people and is challenging to degrade biologically as it has no herbal source. This compound is a contaminant of rising problem (CECs).
