ビス(クロロメチル)エーテル 化学特性,用途語,生産方法
化学的特性
Bis(chloromethyl)ether is a colorless, volatile
liquid with a suffocating odor.
使用
Bis(chloromethyl)ether (BCME) is used asan intermediate in anion-exchange quater nary resins. Its use as a chloromethylationreagent in industry is being discontinuedbecause of its high carcinogenic properties.Exposure risks associated with this com pound can arise during the use or productionof chloromethyl methyl ether when the lat ter compound comes in contact with tracesof water in the presence of hydrogen orhydroxyl ions. It may occur in trace amountsin chloromethyl methyl ether.
一般的な説明
A colorless volatile liquid with a chloroform-like odor. Toxic by inhalation, skin absorption and ingestion. Dangerous fire risk - flash point below 0°F. Vapors much denser than air. Insoluble in water and denser than water. Used to make paints and varnish, and as a solvent.
空気と水の反応
Highly flammable. Insoluble in water. Reacts with water to form hydrochloric acid & formaldehyde.
反応プロフィール
DICHLORODIMETHYL ETHER is incompatible with the following: Acids, water [Note: Reacts with water to form hydrochloric acid & formaldehyde.] .
危険性
A carcinogen. Toxic by ingestion.
健康ハザード
Acute toxicity is high by ingestion, inhalation, and skin irritation. Small quantities may cause death or permanent injury after very short exposure. Chloromethyl ether is an alkylating agent which is a recognized human carcinogen. There is a strong association between industrial exposure and excess lung cancer.
火災危険
Container may explode in heat of fire. When heated to decomposition, BIS(CHLOROMETHYL)ETHER emits very toxic fumes of chlorides. Decomposed by water to hydrochloric acid and formaldehyde. Avoid water: hydrolyzes very rapidly (half life 10-40 seconds) on contact with water. Avoid decomposing heat, powerful oxidizers, areas of high fire hazard and moist air.
発がん性
Bis(chloromethyl) ether (BCME) is known to be human carcinogens based on sufficient evidence of carcinogenicity from studies in humans.
環境運命予測
Chemical/Physical. Reacts rapidly with water forming HCl and formaldehyde (Fishbein, 1979;
Tou et al., 1974). Tou et al. (1974) reported a hydrolysis half-life of 38 sec for sym-dichloromethyl
ether at 20 °C.
Anticipated products from the reaction of sym-dichloromethyl ether with ozone or OH radicals
in the atmosphere, excluding the decomposition products formaldehyde and HCl, are chloromethyl
formate and formyl chloride (Cupitt, 1980).
輸送方法
UN2249 Dichlorodimethyl ether, symmetrical,
Hazard class: 6.1; Labels: 6.1—Poisonous materials, 3—
Flammable liquid.
不和合性
May form explosive mixture with air.
Incompatible with oxidizers (chlorates, nitrates, peroxides,
permanganates, perchlorates, chlorine, bromine, fluorine,
etc.); contact may cause fires or explosions. Keep away
from alkaline materials, strong bases, strong acids, oxoacids,
epoxides. Decomposes on contact with water, moist
air, and heat, forming corrosive hydrochloric acid, hydrogen
chloride, and formaldehyde vapors. May form shocksensitive
compounds on contact with oxidizers, peroxides,
and sunlight. Attacks many plastics.
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.
