DIETHYL ETHER

GENERAL

Diethyl Ether, well-known anesthetic, commonly called simply ether, an organic compound belonging to a large group of compounds called ethers. Ethyl ether is best known as an anesthetic. A highly volatile liquid, it is also used as a solvent, an extractant, and a reaction medium. Methyl ether is used as a spray propellant and refrigerant. The ethers of ethylene glycol are used as solvents and plasticizers.

PRECAUTION IN HANDLING

Flammable liquid and vapors. Keep container closed. Do not breathe vapors. Avoid contact with skin, eyes and mucous membranes. Keep away from heat, sparks and flame. Electrically ground all handling equipment. Protective neoprene or rubber gloves and apron are recommended. Ensure contents are at or below room temperature before opening container(s).
Store in an area designed for storage of flammable liquids.
Protect from temperature extremes and sunlight, and store away from incompatible substances and in accordance with 29 CFR 1910.106. Avoid acids, bases, oxidizers, explosives, nitrogen-fluorine compounds, sulfites, perchlorates.
Flammable liquid and vapor. Once liquid solvent has been completely dispensed, containers which appear "empty" should be handled in the same manner as when they were "full" of liquid solvent.

APPLICATION

It is a widely used solvent for bromine, iodine, most fatty and resinous substances, volatile oils, pure rubber, and certain vegetable alkaloids.

GENERAL DESCRIPTION OF ETHER

Ether is any of a number of organic compounds characterized by an oxygen atom joined by two carbon atoms that are part of hydrocarbon groups. The general formula is ROR', where R and R' are alkyl groups. Ethers are formed by the condensation of two alcohols. They are similar to alcohols but are generally less dense, less soluble in water, and have lower boiling points. They are relatively unreactive chemically. This unreactive property makes ethers valuable as solvents. Common names of ethers simply list the alkyl groups in alphabetical order (ethyl methyl ether, IUPAC name is methoxyethane). Epoxides and crown ethers are a special class of cyclic ethers. Epoxide (oxirane) is a three-membered cyclic ether in which an oxygen atom is joined to each of two carbon atoms that are already bonded to each other. Crown Ether is a macrocyclic polyether whose structure contains hydrogen, carbon and oxygen atoms. Each oxygen atoms are confined between two carbon atoms and exhibits a conformation with a hole (accordingly called "crown").
