Perchloroethane

Perchloroethane is a chemical compound with the formula C2Cl4. It is also known as tetrachloroethylene and commonly referred to as perchloroethylene or P.E. It is a non-flammable, colorless liquid with a characteristic odor. Perchloroethane is a volatile organic compound.

Industrially, perchloroethane is primarily produced by the chlorination of ethylene or other chlorinated hydrocarbons. Its main application is as a solvent, particularly in the dry cleaning industry, where its ability to dissolve grease and oil makes it effective. It is also used as a degreasing agent for metals and in the production of other chemicals.

However, perchloroethane is classified as a toxic substance and a suspected carcinogen. Exposure can occur through inhalation of vapors or skin contact. Health effects associated with exposure can include dizziness, headaches, nausea, and damage to the liver and kidneys. Due to these health and environmental concerns, its use is regulated in many countries, and efforts are ongoing to find safer alternatives. Environmental persistence and potential for groundwater contamination are also significant considerations regarding its use.
