Chemical Properties

Description
Perchloroethylene (Tetrachloroethylene) is a colourless liquid with a slightly ethereal odour. It is marginally soluble in water and soluble in most organic solvents.Perchloroethylene has a limited number of uses and applications. It is used as intermediate, as dry cleaning agent in the industrial and professional sector, as surface cleaning agent in industrial settings, as heat transfer medium in industrial settings, and in film cleaning and copying by professionals. It is also used as a chemical intermediate in the production of fluorinated compounds and in industrial surface cleaning metal degreasing. Occupational exposure to perchloroethylene is possible in the manufacturing facilities or the industrial facilities where it is used as an intermediate.
Appearance
colourless liquid with ether-like odour
Appearance
Tetrachloroethylene is a clear, colorless, nonflammable liquid with a characteristic odor. The odor is noticeable @ 47 ppm, though after a short period it may become inconspicuous, thereby becoming an unreliable warning signal. The Odor Threshold is variously given as 5 ppm to 6.17 (3M).

Safety Profile
Confirmed carcinogen with experimental carcinogenic, and neoplastigenic data. Experimental poison by intravenous route. Moderately toxic to humans by inhalation, with the following effects: local anesthetic, conjunctiva irritation, general anesthesia, hallucinations, distorted perceptions, coma, and pulmonary changes. Moderately experimentally toxic by ingestion, inhalation, intraperitoneal, and subcutaneous routes. An experimental teratogen. Experimental reproductive effects. Human mutation data reported. An eye and severe skin irritant. The liquid can cause injuries to the eyes; however, with proper precautions it can be handled safely. The symptoms of acute intoxication from this material are the result of its effects upon the nervous system. Can cause dermatitis, particularly after repeated or prolonged contact with the skin. Irritates the gastrointestinal tract upon ingestion. It may be handled in the presence or absence of air, water, and light with any of the common construction materials at temperatures up to 140o. Thts material is extremely stable and resists hydrolysis. A common air contaminant. Reacts violently under the proper conchions with Ba, Be, Li, N2O4, metals, NaOH. When heated to decomposition it emits htghly toxic fumes of Cl-. See also CHLORINATED HYDROCARBONS, ALIPHATIC

Hazard Information

General Description
A clear colorless volatile liquid having an ether-like odor. Noncombustible. Insoluble in water. Vapors heavier than air. Density approximately 13.5 lb/gal. Used as dry cleaning solvent, a degreasing solvent, a drying agent for metals, and in the manufacture of other chemicals.
Reactivity Profile
PERCHLOROETHYLENE(127-18-4) decomposes upon heating and exposure to UV light to give phosgene and HCl. Reacts violently with finely dispersed light metals (aluminum) and zinc. [Handling Chemicals Safely 1980 p. 887]. Mixtures with finely divided barium or lithium metal can detonate [ASESB Pot. Incid. 39. 1968; Chem. Eng. News 46(9):38. 1968]. Decomposes very slowly in water to form trichloroacetic acid and hydrochloric acid
Air & Water Reactions
Insoluble in water.
Health Hazard
Vapor can affect central nervous system and cause anesthesia. Liquid may irritate skin after prolonged contact. May irritate eyes but causes no injury.
Potential Exposure
Tetrachloroethylene is used in the textile industry and as a chemical intermediate or a heatexchange fluid; a widely used solvent with particular use as a dry cleaning agent; a degreaser; a fumigant, and medically as an anthelmintic.
Fire Hazard
Special Hazards of Combustion Products: Toxic, irritating gases may be generated in fires.
First aid
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Medical observation is recommended for 24-48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.
Shipping
UN1897 Tetrachloroethylene, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
Incompatibilities
Violent reaction with strong oxidizers; powdered, chemically active metals, such as aluminum, lithium, beryllium, and barium; caustic soda; sodium hydroxide; potash. Tetrachloroethylene is quite stable. However, it reacts violently with concentrated nitric acid to give carbon dioxide as a primary product. Slowly decomposes on contact with moisture producing trichloroacetic acid and hydrochloric acid. Decomposes in UV light and in temperatures above 150℃, forming hydrochloric acid and phosgene.
Waste Disposal
Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal. Incineration, preferably after mixing with another combustible fuel. Care must be exercised to assure complete combustion to prevent the formation of phosgene. An acid scrubber is necessary to remove the halo acids produced. Alternatively, PCE may be recovered from waste gases and reused.

Questions And Answer

Description
Tetrachloroethylene (chemical formula Cl2C=CCl2) is a chlorinate hydrocarbon used as an industrial solvent and cooling liquid in electrical transformers. It is a colorless, volatile, nonflammable liquid with an ether-like odor. The major part of tetrachloroethylene is produced by high temperature chlorinolysis of light hydrocarbons.
Tetrachloroethylene
Tetrachloroethylene is an excellent solvent for organic materials. It is volatile, highly stable, and nonflammable, and thus being widely used in dry cleaning. It can also be used to degrease metal parts in the automotive and other metalworking industries upon being mixed with other chlorocarbons. It can also be used in neutrino detectors. However, it should be noted that it is a potential carcinogen.
Chemical Properties

Uses
Tetrachloroethylene (PCE) is also known as perchloroethylene, tetrachloroethene, and 1,1,2,2- tetrachloroethene and is also commonly abbreviated to PER or PERC. Tetrachloroethylene is a volatile, chlorinated organic hydrocarbon that is widely used as a solvent in the dry-cleaning and textile-processing industries and as an agent for degreasing metal parts. It is an environmental contaminant that has been detected in the air, groundwater, surface waters, and soil (NRC, 2010).
