Perchloroethylene (PCE), also known as tetrachloroethene, is an important organic solvent with the CAS Registry Number 127-18-4.
PCE Chemical Properties:
Perchloroethylene has the molecular formula C₂Cl₄ and appears as a colorless, transparent liquid with an ether-like odor. It has a boiling point of 121°C and a density of 1.622 g/cm³ (at 20°C). It is insoluble in water but miscible with most organic solvents. Perchloroethylene is chemically stable and non-flammable, though it may decompose at high temperatures to produce toxic gases.
Perchloroethylene (PCE) Industrial Applications:
- Dry Cleaning Industry: Used as a primary dry-cleaning solvent due to its strong degreasing power without damaging fabrics.
- Metal Processing: Employed as a metal degreasing and cleaning agent.
- Chemical Manufacturing: Serves as an intermediate in the synthesis of fluorinated hydrocarbons.
- Electronics Industry: Utilized for cleaning precision parts.
Safety Precautions:
Although chemical PCE is widely used in industry, it possesses certain toxic properties. Long-term exposure may cause damage to the liver and nervous system. Proper ventilation systems and protective equipment must be used during handling and operation to ensure safety.
