화학적 성질
Bis(chloromethyl)ether is a colorless, volatile liquid with a suffocating odor.용도
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.일반 설명
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.공기와 물의 반응
Highly flammable. Insoluble in water. Reacts with water to form hydrochloric acid & formaldehyde.반응 프로필
DICHLORODIMETHYL ETHER is incompatible with the following: Acids, water [Note: Reacts with water to form hydrochloric acid & formaldehyde.] .위험도
A carcinogen. Toxic by ingestion.건강위험
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.화재위험
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.Carcinogenicity
Bis(chloromethyl) ether (BCME) is known to be human carcinogens based on sufficient evidence of carcinogenicity from studies in humans.환경귀착
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).

UN2249 Dichlorodimethyl ether, symmetrical, Hazard class: 6.1; Labels: 6.1—Poisonous materials, 3— Flammable liquid.비 호환성
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.폐기물 처리
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.비스(클로로메틸)에테르 준비 용품 및 원자재
