Tetrachloroethylene (PCE), also widely known as perchloroethylene or Perc, is a vital chlorinated organic solvent with the CAS No. 127-18-4 and chemical formula C2Cl4. This colorless, transparent liquid, characterized by its distinctive ether-like odor, plays a crucial role across numerous industrial sectors due to its exceptional solvent properties.

The unique attributes of Tetrachloroethylene include its non-flammability and remarkable chemical stability, even under conditions of high temperature (up to 500°C) when free from air, moisture, and catalysts. PCE boasts a significant relative density of approximately 1.6227 at 20°C, a boiling point of 121°C, and a freezing point of about -22°C. It is readily miscible with common organic solvents such as ethanol, ether, chloroform, and benzene, and possesses the ability to dissolve a wide array of substances, including rubber, resins, fats, and certain inorganic compounds. Its low viscosity and surface tension are particularly advantageous, allowing it to penetrate deeply into materials, which enhances its effectiveness as a cleaning agent.

One of PCE's most prominent and well-recognized applications is in the dry cleaning industry. Unlike conventional washing methods that rely on water, dry cleaning utilizes PCE as the primary solvent. This waterless process is especially suitable for delicate fabrics like silk, wool, velvet, chiffon, velveteen, and natural leather, which are susceptible to damage or changes in shape when exposed to water. PCE efficiently removes organic stains and dirt, dries rapidly, and leaves no residue on the garments. The entire dry cleaning cycle is performed within specialized closed-loop machines, ensuring high efficiency and safety, as the solvent can be regenerated through distillation and reused, making the process more sustainable than it might initially appear.

Beyond its significant role in dry cleaning, Tetrachloroethylene is indispensable for metal degreasing. It effectively removes oils, greases, and other contaminants from metal surfaces, preparing them for subsequent manufacturing processes or finishing treatments. Furthermore, PCE serves as a versatile organic solvent in general industrial applications, an efficient oil extractant, and has historically been used as an insect repellent and a component in fire extinguishing agents and smoke screens. It is also a key intermediate in the synthesis of other valuable chlorinated organic compounds, including trichloroethylene and various fluorinated derivatives. In analytical chemistry, PCE is valued as a solvent for fat or fat-like substances, utilized in techniques such as high-pressure liquid chromatography (HPLC), atomic absorption spectroscopy (AAS), and spectrophotometry.

Despite its broad utility, the handling and application of Tetrachloroethylene necessitate stringent safety protocols due to its potential human health and environmental impacts. PCE is recognized as toxic even at very low concentrations, and chronic exposure can lead to adverse effects such as dizziness, headaches, and damage to the liver and kidneys, with high levels of exposure potentially causing central nervous system damage or more severe health issues, including a suspected carcinogenic risk. Environmentally, it is a persistent contaminant that can infiltrate groundwater and pose risks through vapor intrusion into buildings. Consequently, regulatory landscapes are evolving, with some regions, such as Minnesota, phasing out its use in dry cleaning to encourage the adoption of alternative, safer solvents.
