Details for Perchlorethylene

Perchlorethylene

Category:

Organic chemicals and Derivatives

Perchlorethylene
CAS NO: 127-18-4
EC NO: 204-825-9
Molecular Formula: C2Cl4
Molecular Weight: 165.8334
Specification:
Product description:
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 alkaline: 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 Sex
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.
