化学的特性
Ethylene glycol diethyl ether is a colorless liquid.
使用
Ethylene glycol diethyl ether is a important solvent, used for ink, paint and coating industry. Mainly used in polymer, electrochemistry, boracium chemistry, resin, nitro cellulose, In this product , the benzene, xenene, terphenyl, anthracene reacts with sodium and then bring about the complex; it is also used in surface treatment, halogen analysis in gasoline, acetic acid recycle in diluted acetic acid, depaint agent, thinner, flushing agent, stabilizer, anti oxidant , thickener of lube.
一般的な説明
A clear colorless liquid with a faint ether-like odor. Flash point 95°F. Less dense than water and insoluble in water. Vapors heavier than air.
空気と水の反応
Highly flammable. Insoluble in water.
反応プロフィール
Ethylene glycol diethyl ether can react with oxidizers. Ethylene glycol diethyl ether is incompatible with strong acids.
健康ハザード
Inhalation causes irritation of nose and throat. Contact with liquid irritates eyes but has little or no effect on skin. Ingestion causes irritation of mouth and stomach.
火災危険
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. Mildly toxic by inhalation. An
experimental teratogen. Experimental
reproductive effects. An eye irritant. An
aprotic solvent. A very dangerous fire
hazard when exposed to heat or flame; can
react with oxidizing materials. To fight fire,
use CO2, dry chemical. See also GLYCOL
ETHERS and various cellosolve entries.
職業ばく露
Ethylene glycol diethyl ether is used
as an aprotic solvent; in chemical manufacturing; as a
solvent for detergents and in other cleaning products
輸送方法
UN1153 Ethylene glycol diethyl ether, Hazard
Class: 3; Labels: 3-Flammable liquid
純化方法
After refluxing for 12hours, a mixture of the ether (2L), conc HCl (27mL) and water (200mL), is added with slow passage of nitrogen. The solution is cooled, and KOH pellets are added slowly and with shaking until no more dissolves. The organic layer is decanted, treated with some KOH pellets and again decanted. It is then refluxed with, and distilled from sodium immediately before use. Alternatively, after removal of peroxides by treatment with activated alumina, the ether is refluxed in the presence of the blue ketyl formed by sodium-potassium alloy with benzophenone, then distilled. [Beilstein 1 H 468, 1 II 519, 1 III 2078, 1 IV 2379.]
不和合性
Forms explosive mixture with air when
heated. 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 slowly form unstable reactive peroxides during prolonged storage or on exposure to air and light. Also
incompatible with strong acids; aluminum and its alloys
