Tetrachloroethylene

Basic Information

CAS:127-18-4

HS:29032300

Color, Odor, State: Colorless, transparent liquid with a chloroform-like odor.

Toxicity: Low toxicity

Flammability: Non-flammable

Density: 1.6311

Volatility: Highly volatile

Melting Point: -22.2°C

Boiling Point: 121.2°C

Decomposition: Decomposes easily

Stability: Poor

Autoignition Temperature: 679.3°C

Acidity/Alkalinity: Weakly acidic

Hygroscopicity: Strong

Solubility: Insoluble in water; miscible with ethanol, diethyl ether, and most organic solvents.

Corrosivity: Tetrachloroethylene without stabilizers shows no significant corrosion to common metals when heated to 140°C. However, when exposed to light and prolonged contact with water, it gradually decomposes into trichloroacetic acid and hydrogen chloride, exhibiting corrosive properties.

Application

1. Tetrachloroethylene has diverse applications, primarily serving as a metal degreasing solvent and also as an anthelmintic.

2. It functions as a fat extractant, fire extinguishing agent, and smoke screen agent.

3. Used in synthesizing trichloroethylene and fluorinated organic compounds.

4. Widely employed as a dry cleaning solvent for natural and synthetic fibers.

5. Used as a degreasing detergent for metals, a general-purpose solvent, and an intermediate in organic synthesis.

6. Serves as a standard reference material for chromatographic analysis.

7. Applied as an insecticide in adhesives and a fat extractant.

8. Utilized in organic synthesis.
