Chemical Description 

  • Tetrachloroethylene (PCE), also known as perchloroethylene or "perc," is a synthetic chemical compound with the formula C2Cl4. It is a non-flammable, colorless liquid with a distinctive, somewhat ether-like odor. PCE is widely recognized for its excellent solvent properties, which make it highly valuable across various industrial sectors.
  • In the dry cleaning industry, PCE is the solvent of choice due to its efficiency in removing fats, oils, and greases without damaging fabrics. It is praised for its ability to clean clothes thoroughly while preserving their quality and appearance.
  • The manufacturing sector employs Tetrachloroethylene as a degreaser for metal parts, where its properties help in the removal of organic compounds and preparations of surfaces for further processing.
  • In chemical production, PCE serves as an important intermediate and solvent. It is used in the synthesis of fluorocarbons, which are key in refrigerants and other specialty chemicals.
  • The textile industry utilizes Tetrachloroethylene in the processing and finishing of fabrics. Its application ensures the removal of natural waxes, oils, and impurities, improving the fabric's overall quality.
  • For automotive and industrial equipment, PCE is used in vapor degreasing processes, where its volatilization properties are ideal for cleaning complex machinery components without residue.
  • PCE is also involved in the production of other chemicals, including the manufacture of chlorofluorocarbons (CFCs) and as a feedstock for various organic synthesis processes.
  • Its application extends into the leather industry, where it is used for degreasing raw hides and in the preparation stages of tanning processes.
  • In the environmental sector, Tetrachloroethylene plays a role in soil remediation efforts, helping to extract harmful substances from contaminated sites.
  • Despite its effectiveness as a solvent, the use of PCE is regulated due to environmental and health concerns. It is classified as a potential human carcinogen, and its handling requires strict safety measures to protect workers and the environment.
  • Tetrachloroethylene is an essential chemical solvent with widespread industrial applications. Its effectiveness in cleaning, degreasing, and chemical processing makes it indispensable in many sectors, although its use must be managed responsibly to mitigate health and environmental risks.
