부틸에틸에테르 C화학적 특성, 용도, 생산
화학적 성질
colourless liquid
용도
Extraction solvent, inert reaction medium.
일반 설명
A clear colorless liquid with an ethereal odor. Flash point 40°F. Less dense than water. Vapors heavier than air.
공기와 물의 반응
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].
반응 프로필
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.
위험도
Flammable, dangerous fire risk.
건강위험
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.
화재위험
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.
Safety Profile
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.
잠재적 노출
Used as a solvent for extraction and in
making other chemicals
운송 방법
UN1179 Ethyl butyl ether, Hazard Class: 3;
Labels: 3-Flammable liquid.
Purification Methods
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.]
비 호환성
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.
폐기물 처리
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.
