Diethyl ether Chemical Properties,Uses,Production

Description

Diethyl ether is a component of starting fluids and is used as a solvent in the manufacture of synthetic dyes and plastics. Because of its characteristics, diethyl ether was widely used in many countries as an anesthetic agent, but was then replaced by other substances in the 1960s.

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.

Chemical Properties

Diethyl ether has very diffusive, sweet-ethereal odor. Actually a poor odorant, it gives impression of power by its very high vapor pressure at room temperature.

Physical properties

Colorless, hygroscopic, volatile liquid with a sweet, pungent odor. Odor threshold concentration is 330 ppb (quoted, Keith and Walters, 1992).

History

Ether was supposedly discovered by Raymundus Lullus (1232–1315) around 1275, although there is no extant evidence of this in his writings. The discoverer of ether is often credited to the German physician and botanist Valerius Cordus (1515–1554), who gave the first description of the preparation of ether in the mid-16th century. Cordus called the substance oleum vitrioli dulce, which is translated as sweet oil of vitriol. Cordus used sulfuric acid (oil of vitriol) to catalyze the conversion of alcohol to ether. At approximately the same time Paracelsus (1493–1541), a Swiss physician who is also cited as a discoverer of ether, observed that chickens were safely put to sleep by breathing vapors from sweet oil of vitriol. In 1730, August Siegmund Frobenius changed the name of sweet vitriol to ether.

Uses

Diethyl ether has been used extensively as a general anesthetic.

Uses

Ethyl ether is a solvent that may cause skin irritation. Although considered a non-comedogenic raw material, it is rarely used in cosmetics.
However, being a useful extraction solvent for natural perfume and flavor materials, diethyl ether is often found in traces in the commercial, evaporated extracts. It is easier to remove ether from natural extracts, than it is to remove Hexane and other, more common solvents for perfume raw materials.

Production Methods

Ether is produced by the dehydration of ethanol using sulfuric acid: 2CH₃CH₂OH +2H₂SO₄→ (CH₃CH₂)₂O + H₂SO₄ + H₂O.the temperature of the reaction is carriedout at about 140°C to control for unwanted products.the volatile ether is distilled from themixture. Ether can also be prepared by Williamson synthesis. In this reaction, ethanol reactswith sodium to form sodium ethanolate (Na+C₂H₅O?). Sodium ethanolate then reacts withchloroethane to form ether and sodium chloride: Na+C₂H₅O? +C₂H₅Cl → C₂H₅OC₂H₅ +NaCl. Ether is also produced as a by-product in the production of ethanol.

Definition

diethyl ether: A colourless flammablevolatile ether, C2H5OC2H5; r.d. 0.71;m.p. –116°C; b.p. 34.5°C. It can bemade by Williamson’s synthesis. Itis an anaesthetic and useful organicsolvent.

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)].

Hazard

CNS depressant by inhalation and skin absorption. Very flammable, severe fire and explosion hazard when exposed to heat or flame. Forms explosive peroxides. Explosive limits in air 1.85– 48%.

Health Hazard

The acute toxicity of diethyl ether is low. Inhalation of high concentrations can cause sedation, unconsciousness, and respiratory paralysis. These effects are usually reversible upon cessation of exposure. Diethyl ether is mildly irritating to the eyes and skin, but does not generally cause irreversible damage. Repeated contact can cause dryness and cracking of the skin due to removal of skin oils. The liquid is not readily absorbed through the skin, in part because of its high volatility. Diethyl ether is slightly toxic by ingestion. Diethyl ether is regarded as having adequate warning properties. There is no evidence for carcinogenicity of diethyl ether, and no reproductive effects have been reported. Chronic exposure to diethyl ether vapor may lead to loss of appetite, exhaustion, drowsiness, dizziness, and other central nervous system effects.

Fire Hazard

Diethyl ether is extremely flammable (NFPA rating = 4) and is one of the most dangerous fire hazards commonly encountered in the laboratory, owing to its volatility and extremely low ignition temperature. Ether vapor may be ignited by hot surfaces such as hot plates and static electricity discharges, and since the vapor is heavier than air, it may travel a considerable distance to an ignition source and flash back. Ether vapor forms explosive mixtures with air at concentrations of 1.9 to 36% (by volume). Carbon dioxide or dry chemical extinguishers should be used for ether fires. Diethyl ether forms unstable peroxides on exposure to air in a reaction that is promoted by light; the presence of these peroxides may lead to explosive residues upon distillation.

Flammability and Explosibility

Diethyl ether is extremely flammable (NFPA rating = 4) and is one of the most dangerous fire hazards commonly encountered in the laboratory, owing to its volatility and extremely low ignition temperature. Ether vapor may be ignited by hot surfaces such as hot plates and static electricity discharges, and since the vapor is heavier than air, it may travel a considerable distance to an ignition source and flash back. Ether vapor forms explosive mixtures with air at concentrations of 1.9 to 36% (by volume). Carbon dioxide or dry chemical extinguishers should be used for ether fires. Diethyl ether forms unstable peroxides on exposure to air in a reaction that is promoted by light; the presence of these peroxides may lead to explosive residues upon distillation.

Chemical Reactivity

Reactivity with Water No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

Industrial uses

Diethyl ether as a commercial product is available in several grades and is used as an extraction solvent, reaction solvent, and as a general anesthetic. Ethyl ether is an excellent solvent for alkaloids, dyes, fats, gums, oils, resins, and waxes. Blends of ethyl ether and ethanol are excellent solvents for cellulose nitrate used in the manufacture of guncotton, in collodion solutions and pyroxylin plastics. Ethyl ether is used in the recovery of acetic acid from aqueous solutions in the cellulose acetate and plastic industry. It is used as a starter fuel for diesel engines and as a denaturant in denatured ethanol formulations. Grignard and Wurtz-Fillig synthesis reactions use diethyl ether as an anhydrous, inert reaction medium.

Potential Exposure

Ethyl ether is used as a solvent for waxes, fats, oils, perfumes, alkaloids, dyes, gums, resins, nitrocellulose, hydrocarbons, raw rubber, and smokeless powder. It is also used as an inhalation anesthetic; a refrigerant; in diesel fuels; in dry cleaning; as an extractant; and as a chemical reagent for various organic reactions

Environmental Fate

Photolytic. The rate constant for the reaction of ethyl ether and OH radicals in the atmosphere at 300 K is 5.4 x 10^-12 cm³/molecule?sec (Hendry and Kenley, 1979).
Chemical/Physical. The atmospheric oxidation of ethyl ether by OH radicals in the presence of nitric oxide yielded ethyl formate as the major product. Minor products included formaldehyde and nitrogen dioxide. In the absence of nitric oxide, the products were ethyl formate and acetaldehyde (Wallington and Japar, 1991).
Ethyl ether will not hydrolyze (Kollig, 1993).

storage

ether should be used only in areas free of ignition sources (including hot plates, incandescent light bulbs, and steam baths), and this substance should be stored in tightly sealed metal containers in areas separate from oxidizers. Because of the tendency of diethyl ether to form peroxides on contact with air, containers should be dated upon receipt and at the time they are opened. Diethyl ether is generally supplied with additives that inhibit peroxide formation; distillation removes these inhibitors and renders the liquid more prone to peroxide formation. Material found to contain peroxides should be treated to destroy the peroxides before use or disposed of properly.

Shipping
