化学的特性

colourless to light yellow liquid with a chloroform-like

化学的特性

Tetrachloroethane is a heavy, volatile colorless to light yellow liquid. It has a sweetish, chloroform-like odor. The Odor Threshold is 0.5 ppm in water and 1.5 ppm in air.

使用

Nonflammable solvent for fats, oils, waxes, resins, cellulose acetate, rubber, copal, phosphorus, sulfur. As solvent in certain types of Friedel-Crafts reactions or phthalic anhydride condensations. In the manufacture of paint, varnish, and rust removers. In soil sterilization and weed killer and insecticide formulations. In the determination of theobromine in cacao. As immersion fluid in crystallography. In the biological laboratory to produce pathological changes in gastrointestinal tract, liver, and kidneys. Intermediate in the manufacture of trichloroethylene and other chlorinated hydrocarbons having two carbon atoms.

定義

ChEBI: A member of the class of chloroethanes that is ethane substituted by chloro groups at positions 1, 1, 2 and 2.

一般的な説明

Colorless to pale yellow liquid with a sweet odor. Sinks in water.

空気と水の反応

Insoluble in water.

反応プロフィール

1,1,2,2-Tetrachloroethane may be incompatible with strong oxidizing and reducing agents. Also may be incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides. Decomposed by heat and UV light, forming phosgene and HCl; reacts violently with finely dispersed metals [Handling Chemicals Safely 1980. p. 886].

危険性

Toxic by ingestion, inhalation, skin absorption. Questionable carcinogen.

健康ハザード

Compound is a powerful narcotic and liver poison; may also cause changes in blood composition and neurological disturbances. Repeated exposure by inhalation can be fatal. Ingestion causes vomiting, diarrhea, severe mucosal injury, liver necrosis, cyanosis, unconsciousness, loss of reflexes, and death. Contact with eyes causes irritation and lachrymation. Can be absorbed through the skin and may produce severe skin lesions.

火災危険

Special Hazards of Combustion Products: Irritating hydrogen chloride vapor may form in fire.

安全性プロファイル

Suspected carcinogen with experimental carcinogenic and tumorigenic data. Poison by inhalation, ingestion, and intraperitoneal routes. Moderately toxic by several other routes. Mutation data reported. Human central nervous system effects by ingestion and inhalation: general anesthesia, somnolence, hallucinations, and distorted perceptions. Considered the most toxic of the common chlorinated hydrocarbons. Considered to be a very severe industrial hazard and its use has been restricted or even forbidden in certain countries. It is not an inert solvent. Reacts violently with N2O4,2,4dinitrophenyl disulfide, and on contact with sodium or potassium. When heated in contact with solid potassium hydroxide, spontaneously flammable chloroor dichloroacetylene gas is evolved. Any water can cause appreciable hydrolysis, even at room temperature, and both hydrolysis and oxidation become comparatively rapid above 110'. When heated to decomposition it emits toxic fumes of Cl-. A strong irritant of eyes and mucous membranes. A concentration of 3 ppm produces a detectable odor, thus an initial produces a detectable odor, thus an initial warning effect. Its narcotic action is stronger than that of chloroform, but, because of its low volatility, narcosis is less severe and much less common in industrial poisoning than in the case of other chlorinated hydrocarbons. The toxic action of this material is chiefly on the liver, where it produces acute yellow atrophy and cirrhosis. Fatty degeneration of the kidneys and heart, hemorrhage into the lungs and serous membranes, and edema of the brain have also been found in fatal cases. Some reports indicate a toxic action on the central nervous system with changes in the brain and in the peripheral nerves. The effect on the blood is one of hemolysis with appearance of young cells in the circulation and a monocptosis. Due to its solvent action on the natural skin oils, dermatitis is not uncommon. The initial symptoms resulting from exposure to the vapor are lachrymation, salivation, and irritation of the nose and throat. Continued exposure to high concentrations results in restlessness, dizziness, nausea, vomiting, and narcosis. The latter, however, is rare in industry. More commonly, exposure is less severe and most complaints are vague and related to the digestive and nervous systems. The patient's symptoms gradually progress to a more serious illness with development of toxic jaundice, liver tenderness, etc., and possibly albuminuria and edema. With serious liver damage, the jaundice increases and toxic symptoms appear, with somnolence, delirium, convulsions, and coma usually precedmg death. See also ACETYLENE COMPOUNDS and CHLORIDES.

職業ばく露

Tetrachloroethane is used as an intermediate in the trichloroethylene production from acetylene and as a solvent; as a dry cleaning agent; as a fumigant; in cement; and in lacquers. It is used in the manufacture of artificial silk, artificial leather, and artificial pearls. Recently, its use as a solvent has declined due to replacement by less toxic compounds. It is also used in the estimation of water content in tobacco and many drugs, and as a solvent for chromium chloride impregnation of furs.

応急処置

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.

輸送方法

UN1702 Tetrachloroethane or 1,1,2,2Tetrachloroe thane, Hazard Class: 6.1; Labels: 6.1Poisonous materials.

純化方法

Stir the ethane, on a steam-bath, with conc H2SO4 until a fresh portion of acid remains colourless. The organic phase is then separated, distilled in steam, dried (CaCl2 or K2CO3), and fractionally distilled in a vacuum. [Beilstein 1 IV 144.]

不和合性

Violent reaction with chemically active metals; strong caustics; strong acids; especially fuming sulfuric acid. Degrades slowly when exposed to air. Attacks plastic and rubber.

廃棄物の処理

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.
