化学的特性
CLEAR LIQUID
物理的性質
Colorless liquid with a mild, ether-like odor. Experimentally determined detection and recognition
odor threshold concentrations were 1.6 mg/m
3 (330 ppb
v) and 3.1 mg/m
3 (640 ppb
v), respectively
(Hellman and Small, 1974).
使用
Industrial solvent.
一般的な説明
A clear colorless liquid with a pleasant odor. Flash point of 135°F. Denser than water and soluble in water. Vapors are heavier than air.
空気と水の反応
Flammable. Water soluble. Reacts slowly in water to form acetic acid and methyl alcohol; the reaction is not violent.
反応プロフィール
Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.
危険性
Toxic by ingestion, inhalation, and skin
absorption. Moderate fire risk. Toxic by skin
absorption.
健康ハザード
May cause irritation if splashed into eyes. Can be absorbed through the skin. Swallowing a large single dose or absorbing larged amount through skin could result in death. It is unlikely that air levels of the compound would be dangerous unless it is heated.
火災危険
Special Hazards of Combustion Products: Irritating vapors and toxic gases, such as carbon monoxide, may be formed when involved in fire.
安全性プロファイル
Moderately toxic by
ingestion, intraperitoneal, and subcutaneous
routes. hfddly toxic by inhalation and skin
contact. Human systemic effects by
inhalation: eye lachrymation, cough, and
pulmonary changes. Experimental
reproductive effects. Mutation data
reported. An inhalation irritant in humans.
An eye irritant. Flammable liquid when
exposed to heat or flame; can react with
oxidizing materials. A moderate explosion
hazard. To fight fire, use CO2, dry chemical.
When heated to decomposition it emits
acrid smoke and irritating fumes. See also
GLYCOL ETHERS.
職業ばく露
Methoxyethyl acetate is used as
a solvent for resins, oils, greases and inks. It is also an
ingredient of lacquers, paints and adhesives.
環境運命予測
Chemical/Physical. Hydrolyzes in water forming methyl cellosolve and acetic acid.
At an influent concentration of 1,024 mg/L, treatment with GAC resulted in an effluent
concentration of 886 mg/L. The adsorbability of the carbon used was 28 mg/g carbon (Guisti et
al., 1974).
輸送方法
UN1189 Ethylene glycol monomethyl ether
acetate, Hazard Class: 3; Labels: 3-Flammable liquid.
純化方法
Shake the methoxy-ethane with anhydrous Na2CO3, filter and distil it in a vacuum. Redistillation can be then be carried out at atmospheric pressure. [Dunbar & Bolstad J Org Chem 21 1041 1956, Beilstein 2 IV 214.]
廃棄物の処理
Dissolve or mix the material
with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal,
state, and local environmental regulations must be
observed. Beware of possible presence of peroxides in
which case open burning may be used
