Tetrachloroethylene
Tetrachloroethylene
Tetrachloroethylene (pronunciation: tet-ra-klor-o-eth-uh-leen), also known as perchloroethylene or PCE, is a colorless, volatile, nonflammable liquid widely used in dry cleaning and metal degreasing operations.
Etymology
The term "tetrachloroethylene" is derived from the Greek words "tetra" meaning four, "chloros" meaning green, and "ethylene" which is a common organic compound. This refers to the four chlorine atoms attached to the two carbon atoms of the ethylene molecule.
Usage
Tetrachloroethylene is primarily used in the dry cleaning industry as a solvent for cleaning fabrics. It is also used in the metal degreasing process due to its ability to dissolve greases, oils, and waxes without affecting the metal underneath.
Health Effects
Exposure to high concentrations of tetrachloroethylene can cause dizziness, headaches, sleepiness, confusion, nausea, difficulty in speaking and walking, unconsciousness, and even death. Long-term repeated exposure can lead to mood changes, memory loss, and damage to the liver, kidneys, and reproductive systems.
