Physical and chemical properties Color and odor status: colorless, transparent, chloroform-like odor liquid.
Toxicity: low toxicity Flammability: non-flammable
Density: 1.6311 Volatility: extremely volatile
Melting point: -22.2°C Boiling point: 121.2℃
Decomposability: easy to decompose Stability: poor
Auto-ignition point: 679.3℃ Acidity and alkalinity: weak acidity
Hygroscopicity: strong  
Solubility: insoluble in water, miscible in most organic solvents such as ethanol and ether.
Corrosivity: Tetraene without stabilizer is heated to 140℃ and has no obvious corrosion to common metals. When tetraene without stabilizer is in contact with water for a long time under the action of light, it will gradually generate trichloroacetic acid and hydrogen chloride, causing corrosion.

Uses Perchloroethylene has a wide range of uses, mainly used as a metal degreasing solvent, and also used as an intestinal worm agent. Perchloroethylene can be used as a fat extraction agent, fire extinguishing agent and smoke screen agent, etc., and can also be used to synthesize trichloroethylene and fluorine-containing organic compounds; widely used as a dry cleaning agent for natural and synthetic fibers; also used as a degreasing and washing agent for metals Repellent and general solvents, organic synthesis intermediates, etc.; used as standard materials for chromatographic analysis; used as insect repellents for adhesives, fat extractants, and also used in organic synthesis.
Hazard category Class 6.1 poison
Fire-fighting measures This thing is not combust
Emergency treatment Skin contact: Take off contaminated clothing immediately, rinse the skin thoroughly with soap and water, and seek medical attention; Eye contact: Lift the eyelids, rinse with running water or normal saline, and seek medical attention; Inhalation: Leave the scene quickly to a place with fresh air and keep the respiratory tract unobstructed If breathing is difficult, give oxygen. If breathing stops, give artificial respiration and seek medical treatment immediately; Ingestion: drink enough warm water, induce vomiting, and seek medical treatment.
Packaging, storage, transportation It can be packaged in inner galvanized, painted iron drums (300-320kg/drum), stainless steel tanks; the warehouse is ventilated, low-temperature and dry; stored separately from oxidants and food additives; stored in a cool, ventilated warehouse. Keep away from fire and heat sources. The packaging must be sealed and not in contact with air. It should be stored separately from alkalis, active metal powders, alkali metals, and edible chemicals, and avoid mixed storage.
