Tetrachloroethylene, also known as perchloroethylene, is an organic chemical that is widely used in dry cleaning and metal degreasing, and is also used in the manufacture of other chemicals and consumer products. It is a non-flammable liquid at room temperature. It is easy to volatilize and has a stimulating sweet taste. Many people can smell when the air contains one part per million of tetrachloroethylene. In 1821, Michael Faraday heated hexachloroethane for the first time to decompose it into tetrachloroethylene and chlorine. Specification Control LCCN: sh95000495 GND: 4184861-5 NDL: 01120522
