1,1-ジクロロエタン (安定剤:ニトロメタン) 化学特性,用途語,生産方法

用途

製造用剤

化学的特性

Also ethylidene chloride,CH3CHCl2 is a colorless,neutral,mobile liquid with an aromatic ethereal odor and saccharin taste. Soluble in alcohol, ether,fixed and volatile oils and very sparingly soluble in water. It is used as an extraction solvent and fumigant.

化学的特性

1,1-Didichloroethane is a colorless, oily liquid with a chloroform-like odor.

物理的性質

Clear, colorless, oily liquid with a chloroform-like odor

使用

Ethylidene dichloride is primarily used as an intermediate in chemical synthesis. Acute (short-term) inhalation exposure to high levels of ethylidene dichloride in humans results in central nervous system (CNS) depression and a cardiostimulating effect resulting in cardiac arrhythmias. Studies in animals have reported effects on the kidney. No information is available on the chronic (long-term) reproductive, developmental, or carcinogenic effects of ethylidene dichloride in humans. An oral animal study reported a significantly positive dose-related trend in hemangiosarcomas, mammary tumors, liver tumors, and endometrial stromal polyps. EPA has classified ethylidene dichloride as a Group C, possible human carcinogen.
Primary uses are:
Ethylidene dichloride is primarily used as an intermediate in the manufacture of other chemicals such as vinyl chloride and 1,1,1- trichloroethane, and to manufacture high vacuum rubber.
Ethylidene dichloride has limited use as a solvent for plastics, oils, and fats.
In the past, ethylidene dichloride was used as an anesthetic, but that use has been discontinued.
Ethylidene dichloride is a colorless oily liquid which is very volatile. It has an odor similar to ether; the odor threshold is 120 parts per million (ppm).

使用

1,1-Dichloroethane is used as a chemical solvent in the preparation of precursors of quinolizine, isoquinoline and indole alkaloids.

使用

Solvent for paint, varnishes; degreaser. Has been used as a surgical anesthetic.

一般的な説明

A colorless liquid with an ether-like odor. Slightly soluble in water and slightly denser than water. Flash point below 70°F. Vapors denser than air. Used to make other chemicals.

空気と水の反応

Highly flammable. Slightly soluble in water.

反応プロフィール

1,1-DICHLOROETHANE can react vigorously with oxidizing materials. 1,1-DICHLOROETHANE is incompatible with strong bases. Contact with strong caustics will cause formation of flammable and toxic gas. 1,1-DICHLOROETHANE will attack some forms of plastics, rubber and coatings.

危険性

Toxic. Eye and upper respiratory tract irritant; kidney and liver damage. Questionable carcinogen.

健康ハザード

INHALATION: Irritation of respiratory tract. Salivation, sneezing, coughing, dizziness, nausea, and vomiting. EYES: Irritation, lacrimation, and reddening of conjunctiva. SKIN: Irritation. Prolonged or repeated skin contact can produce a slight burn. INGESTION: Ingestion incidental to industrial handling is not considered to be a problem. Swallowing of substantial amounts could cause nausea, vomiting, faintness, drowsiness, cyanosis, and circulatory failure.

安全性プロファイル

Moderately toxic by ingestion. Experimental teratogenic effects. Questionable carcinogen with experimental tumorigenic data. Liver damage reported in experimental animals. A very dangerous fire hazard and moderate explosion hazard when exposed to heat or flame; can react vigorously with oxidizing materials. To fight fire, use alcohol foam, water, foam, CO2, dry chemical. When heated to decomposition it emits highly toxic fumes of phosgene and Cl-

職業ばく露

It is used as a solvent; cleaning and degreasing agent; as well as in organic synthesis as an intermediate

環境運命予測

Biological. 1,1-Dichloroethane showed significant degradation with gradual adaptation in a static-culture flask-screening test (settled domestic wastewater inoculum) conducted at 25 °C. At concentrations of 5 and 10 mg/L, percent losses after 4 wk of incubation were 91 and 83, respectively. At a substrate concentration of 5 mg/L, 19% was lost due to volatilization after 10 d (Tabak et al., 1981). Under anoxic conditions, indigenous microbes in uncontaminated sediments produced vinyl chloride (Barrio-Lage et al., 1986).
Surface Water. The following volatilization half-lives were reported for 1,1-dichloroethane: 6 to 9 d in a pond, 5 to 8 d in a lake, 24 to 32 h in a river (Smith et al., 1980).
Photolytic. Titanium dioxide suspended in an aqueous solution and irradiated with UV light (λ = 365 nm) converted 1,1-dichloroethane to carbon dioxide at a significant rate (Matthews, 1986). The initial photodissociation product of 1,1-dichloroethane was reported to be chloroacetyl chloride (U.S. EPA, 1975). This compound is readily hydrolyzed to HCl and chloroacetic acid (Morrison and Boyd, 1971).
The rate constant for the reaction of 1,1-dichloroethane and OH radicals in the atmosphere at 300 K is 1.6 x 10-11 cm3/molecule?sec (Hendry and Kenley, 1979). At 296 K, a photooxidation rate constant of 2.6 x 10-13 cm3/molecule?sec was reported for the reaction with OH radicals resulting in a half-life of 1.5 months (Howard and Evenson, 1976).
Chemical/Physical. A glass bulb containing air and 1,1-dichloroethane degraded outdoors to carbon dioxide and HCl. The half-life for this reaction was 17 wk (Pearson and McConnell, 1975). Hydrolysis of 1,1-dichloroethane under alkaline conditions yielded vinyl chloride, acetaldehyde, and HCl (Kollig, 1993). The reported hydrolysis half-life at 25 °C and pH 7 is 61.3 yr (Jeffers et al., 1989).

輸送方法

UN2362 1,1-Dichloroethane, Hazard Class: 3; Labels: 3-Flammable liquid

純化方法

Shake it with conc H2SO4 or aqueous KMnO4, then wash it with water, saturated aqueous NaHCO3, again with water, dry with K2CO3 and distil it from CaH2 or CaSO4. Store it over silica gel. [Beilstein 1 IV 130.]

不和合性

Vapor may form explosive mixture with air. Reacts violently with strong oxidizers, alkali metals; earth-alkali metals; powdered metals; causing fire and explosion hazard. Contact with strong caustic will produce flammable and toxic acetaldehyde gas. Attacks aluminum, iron. Attacks some plastics (including polyethylene) and coatings.

廃棄物の処理

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. 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
