Diethyl ether Chemical Properties,Uses,Production

Chemical Properties

Diethyl ether is inactive at room temperatures, but some reactions may also occur. Peroxides are prone to prolonged exposure to oxygen (or light) to become ether peroxide (also known as ether hydroperoxide). Peroxide ether is a viscous liquid that hardly evaporates. Antioxidants are often added in storage of ether to avoid the slow oxidation. Diethyl ether will crack in case of being oxidized violently. In the presence of catalysts, it can break down into aldehydes or acids. It reacts with an organic acid anhydride to form an ester in the presence of a catalyst, or reacts with an inorganic acid anhydride to form an ester without any catalyst. It can react with metal halides to produce addition compounds such as cerium chloride adduct 2(C2H5)2O•BeCl2. It can react with halogen to produce monohalogenated ethers and polyhaloethers. Ether can react with sulfuric acid generating an adduct.

Medical uses

It can be used to test the arm-to-lung blood circulation time. After being injected into the upper arm vein, the drug liquid goes from the right atrium, passes right ventricle to reach the lungs, and is then discharged from the respiratory tract. It normally takes 4 to 6 seconds for the patients to smell ether odor from the infusion moment (or 3 to 8 seconds).

【Usage and Dosage】
【Specifications】 Injection: 3ml.




Diethyl ether is produced by dehydrating ethanol at 300 °C in the presence of catalyst.

Chemical Properties

Ether, (C2H5)2,also known as ethyl ether, is a colorless liquid. It is used as a solvent,a denaturant, and as an anesthetic in medicine. lt is an organic compound in which two hydrocarbon radicals are joined by an atom of oxygen.


ChEBI: An ether in which the oxygen atom is linked to two ethyl groups.


Solvent for waxes, fats, oils, perfumes, alkaloids, gums. Excellent solvent for nitrocellulose when mixed with alcohol. Important reagent in organic syntheses, especially in Grignard and Wurtz type reactions. Easily removable extractant of active principles (hormones, etc.) from plant and animal tissues. In the manufacture of gun powder. As primer for gasoline engines.

General Description

A clear colorless liquid with an anesthetic odor. Flash point -49°F. Less dense than water and slightly soluble in water. Hence floats on water. Vapors are heavier than air. Used as a solvent and to make other chemicals.

Air & Water Reactions

Highly flammable. 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)].

Reactivity Profile

Occasional explosions have occurred when aluminum hydride was stored in ether. The explosions have been blamed on the presence of carbon dioxide impurity in the ether, [J. Amer. Chem. Soc. 70:877(1948)]. Diethyl ether and chromium trioxide react violently at room temperature. Solid acetyl peroxide in contact with ether or any volatile solvent may explode violently. A 5-gram portion in ether detonated while being carried, [Chem. Eng. News 27:175(1949)]. Nitrosyl perchlorate ignites and explodes with Diethyl ether. A mixture of ether and ozone forms aldehyde and acetic acid and a heavy liquid, ethyl peroxide, an explosive, [Mellor 1:911(1946-1947)].

Health Hazard

Vapor inhalation may cause headache, nausea, vomiting, and loss of consciousness. Contact with eyes will be irritating. Skin contact from clothing wet with the chemical may cause burns.

Fire Hazard

Behavior in Fire: Vapor is heavier than air and may travel considerable distance to a source of ignition and flash back. Decomposes violently when heated.

Purification Methods

Usual impurities are water, EtOH, diethyl peroxide (which is explosive when concentrated), and aldehydes. Peroxides [detected by liberation of iodine from weakly acid (HCl) solutions of KI, or by the blue colour in the ether layer when 1mg of Na2Cr2O7 and 1 drop of dilute H2SO4 in 1mL of water is shaken with 10mL of ether] can be removed in several different ways. The simplest method is to pass dry ether through a column of activated alumina (80g Al2O3/700mL of ether). More commonly, 1L of ether is shaken repeatedly with 5-10mL of a solution comprising 6.0g of ferrous sulfate and 6mL of conc H2SO4 in 110mL of water. Aqueous 10% Na2SO3 or stannous chloride can also be used. The ether is then washed with water, dried for 24hours with CaCl2, filtered and dried further by adding sodium wire until it remains bright. The ether is stored in a dark cool place, until distilled from sodium before use. Peroxides can also be removed by wetting the ether with a little water, then adding excess LiAlH4 or CaH2 and leaving to stand for several hours. (This also dried the ether.) Werner [Analyst 58 335 1933] removed peroxides and aldehydes by adding 8g AgNO3 in 60mL of water to 1L of ether, then 100mL of 4% NaOH and shaking for 6minutes. Fierz-David [Chimia 1 246 1947] shook 1L of ether with 10g of a zinc-copper couple. (This reagent is prepared by suspending zinc dust in 50mL of hot water, adding 5mL of 2M HCl and decanting after 20seconds, washing twice with water, covering with 50mL of water and 5mL of 5% cuprous sulfate with swirling. The liquid is decanted and discarded, and the residue is washed three times with 20mL of ethanol and twice with 20mL of diethyl ether). Aldehydes can be removed from diethyl ether by distillation from hydrazine hydrogen sulfate, phenyl hydrazine or thiosemicarbazide. Peroxides and oxidisable impurities have also been removed by shaking with strongly alkaline-saturated KMnO4 (with which the ether was left to stand in contact for 24hours), followed by washing with water, conc H2SO4, water again, then drying (CaCl2) and distillation from sodium, or sodium containing benzophenone to form the ketyl. Other purification procedures include distillation from sodium triphenylmethide or butyl magnesium bromide, and drying with solid NaOH or P2O5. [Beilstein 1 IV 1314.] Rapid purification: Same as for 1,4-dioxane.
