ブチルエチルエーテル 化學(xué)特性,用途語,生産方法
外観
無色～微黃色の液體
用途
溶剤、有機(jī)合成原料。
化學(xué)的特性
colourless liquid
使用
Extraction solvent, inert reaction medium.
一般的な説明
A clear colorless liquid with an ethereal odor. Flash point 40°F. Less dense than water. Vapors heavier than air.
空気と水の反応
Highly flammable. Slightly soluble in water. Oxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick 1979. p.151-154, 164]. A mixture of liquid air and diethyl ether exploded spontaneously [MCA Case History 616. 1960].
反応プロフィール
Ethers, such as Butyl ethyl ether, can act as bases. They form salts with strong acids and addition complexes with Lewis acids. The complex between diethyl ether and boron trifluoride is an example. Ethers may react violently with strong oxidizing agents. In other reactions, which typically involve the breaking of the carbon-oxygen bond, ethers are relatively inert.
危険性
Flammable, dangerous fire risk.
健康ハザード
Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control may cause pollution.
火災(zāi)危険
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
安全性プロファイル
Moderately toxic by
ingestion. A skin and eye irritant. A very
dangerous fire hazard when exposed to heat
or flame; can react vigorously with oxidizing
materials. Keep away from heat and open
flame. To fight fire, use alcohol foam, CO2,
dry chemical. When heated to
decomposition it emits acrid smoke and
irritating fumes. See also ETHERS.
職業(yè)ばく露
Used as a solvent for extraction and in
making other chemicals
輸送方法
UN1179 Ethyl butyl ether, Hazard Class: 3;
Labels: 3-Flammable liquid.
純化方法
Purify by drying with CaSO4, by passage through a column of activated alumina (to remove peroxides), followed by prolonged refluxing with Na and then fractional distillation. [Beilstein 4 IV 1518.]
不和合性
May form explosive mixture with air.
Heat or prolonged storage may cause the formation of unstable peroxides. 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, and epoxides. Attacks some plastics,
rubber and coatings. May accumulate static electrical
charges, and may cause ignition of its vapors.
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. 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.
